How long does it take your radiant heat system to warm up - how long does radiant heat take to warm up
In the case where the desired mean velocity of the fluid flow is known as well as the required volume flow through the pipe, the inner diameter of the pipe can be calculated according to the following:
A water heater pressure relief valve, also referred to as a T&P valve, pressure relief valve, or water heater temperature valve is a safety feature that you can find on any water heater. The reason it’s there is to keep you safe in case the water pressure is too high.
In order to find a solution to your fluid flow problem, you need to download the calculator and open the solutions you can download here.
Fortunately, by understanding how relief valves work, you can solve whatever problem you’re having with the one on your water heater. In this article, we’ll review everything you should know about this valve.
If your valve is sticky, then it becomes stuck in a closed (downward) or open (extended position). If it’s closed, then the valve won’t be able to relieve the heat or pressure that builds up in the closed water heater system. There could be a rupture as a result.
If you’ve been having issues with your water heater recently, this article is for you! You might find that you’re paying high energy bills, not getting access to hot water when you want it, or your water pressure is low. This can be frustrating, but what’s the cause? You might be having a problem with the water heater pressure relief valve.

The velocity of fluid flow is calculated as the ratio between the flow of fluid and the cross-sectional area of the tube. The magnitude calculated in this way is the mean value of the fluid velocity. The actual velocity of the fluid in the pipe is not uniform across the cross-sectional area. The velocity of fluid flow is greatest in the axis of the pipeline, and is equal to zero at the point of contact between the fluid and the pipe wall. The mean velocity of fluid flow can be calculated as follows:
The water heater pressure valve is in place so that it can relieve excess pressure and temperature in a water heater if either of these is too high. Because this everyday appliance is a closed system, thermal expansion occurs in water heaters.
This is for safety reasons. Everything has been done according to standards that have been mandated by plumbing codes. So if you’re having any issues with the valve, you’ll have to call a professional to have it fixed.
where is: D - internal pipe diameter; q - volumetric flow rate; v - velocity; A - pipe cross section area.
Each example was solved using a calculator and the example solution shown was obtained by simply entering known quantities into the calculator, selecting units of measure and type of calculation.
When, instead of the volume flow, the mass flow rate and the desired fluid flow rate are known, the internal diameter of the pipe can be determined as follows:

The examples presented and their solutions are intended to present the possibility of calculator application in solving fluid flow problems in pipes.
To get started, identify where the relief valve shut off is. Usually, you can find it upon the cold water feed, which is on top of the water tank, on the right side where the inlet is.
To avoid draining the hot water heater or replacing the valve every so often, install the Corro-Protec powered anode to solve those two issues.

Task: Calculate the diameter of the carbon dioxide pipe with a flow rate of 10 kg/h and a velocity 2 m/s at a pressure of 7 bar absolute and a temperature of 20 °C.
However, when the temperature is 210 degrees—or the pressure is 150 psi (pounds per square inch)—t his is far too much pressure and heat in the water heater tank. If it’s the case, you should change your hot water heater temperature or verify your heater thermostat.
When your water heater pressure relief valve isn’t functioning properly, it’s usually for one of two reasons. It either sticks so that it doesn’t properly open or close, or it has a leak, which means that it’s continually dripping, lowering your water pressure.
Here’s how it works. Whether your water heater is heated by electric heating elements or a gas burner, both the metal tank and the water inside expand when the hot water temperature is somewhere between 120 and 140 degrees.

If you suspect there’s a problem with your water heater pressure relief valve, you can do a test. This is actually a good idea if you don’t have any problems at all, as this type of maintenance will protect your water heater—and yourself.
Finally, you can get hot water at the right pressure again, enjoying your morning shower like you used to. Read on to learn more.

If you’ve been noticing any issues with your water heater pressure relief valve, then you need to know where it is on your water heater. Usually, you can find it on the top or side of this appliance. The valve connects to a plastic or metal discharge tube that runs down the side of the tank.
This valve also ensures that there aren’t any leaks in your water heater, which would lead to low water pressure when you want to use it to wash the dishes or take a shower.
This said, considering that there might be other issues causing discharge tube problems—issues connected to high water pressure or temperature—it’s safest to have a professional deal with this too.
On the right side you can find three examples showing how you can calculate the pipe diameter if fluid flow and flow rate are known.
This said, if you’re only having issues with the discharge tube, this is easy to replace. You won’t have to drain your water heater, and you can deal with it yourself.
If a water pressure issue is what is causing the water heater pressure relief valve to not work, then it might be dangerous for you to change the valve yourself. Generally speaking, it’s a good idea to hire a professional to protect yourself.

Pipe diameter calculator allows you to calculate pipe diameter for known fluid flow and flow rate, as well as stream speed for known pipe flow and diameter. The calculator also allows conversion between volume and mass flow. With the help of a calculator you can calculate the volume flow of an ideal gas at different pressures and temperatures.
Without this safety feature, your water heater could end up breaking. You could potentially end up with burns if the high water pressure is dangerously high.

If your valve is working, this is when it will open. This releases steam and hot water from the discharge tube, making your water heater operate safely again.
Sometimes, you can easily fix this problem by opening and closing the valve lever a few times. However, if it continues to stick, then you’ll need to replace it.
Your water heater is leaking? Make sure that it doesn’t come from the valve before replacing it. If your pressure relief valve is leaking, then this may be because it isn’t seated properly in the tank’s threaded opening. This is quite a common issue if you’ve recently replaced your old valve with a new one.

Finally, release the level so that it quickly snaps into the original position. If it doesn’t snap quickly into this original position, then your water heater valve isn’t working and needs to be replaced.
Once you’ve done this, take a look at the discharge tube to make sure that it’s attached firmly. Then, take a bucket and put it under the discharge tube.
Task: Calculate the pipe diameter if the water flow velocity is 1 m/s and the flow rate is 5 lit/min
Now, pull the metal lever of the valve slightly, so that a small amount of the water—a quarter cup or so—discharges into the bucket.
A water heater pressure relief valve, also referred to as a T&P valve, or water heater temperature valve is a safety feature that you can find on all water heaters. The reason it’s there is to keep you safe in case the water pressure gets too high.

The water heater pressure is already installed when you receive your water heater (or buy a home that has one already). It’s actually welded onto the tank; you’ll see a threaded inlet where it is.
