It's difficult to calculate. Depending on the valve pressure, temperature, density, etc., the empirical selection is carried out according to the flow rate. Flow Rate (m/s): Liquid: 2 to 3. If you use flow rate 2 or 3, multiply it by the cross-sectional area of the valve seat, then multiply it by the valve opening, you can estimate approximately the amount of water you run in an hour.
Solar water temperature
3 tons of water. Solar water supply equipment with a flow rate of 1 cubic meter/hour is used during the water supply process, the water pipe diameter and water flow speed remain unchanged and the density of water is 1000 kg/m². Then the amount of water obtained after filling the water for 3 hours is: 1 cubic meter/hour * 3 hours = 3 cubic meters. 3 cubic meters = 3 tons.
One hour of work = 1,500 × 3,600 = 5,400,000
The donkeyrgy required to raise the temperature of 180 L of water by 1 degree = 180 × 1000 × 4.2 = 756,000
< p>Dividing one equals 7.1 degrees, we can see that the heats -solar water heaters use electric heating very slowly2000 W equals 7.1*2000/1500 = 9.5 degrees
The general temperature of tap water is 15 degrees, and you can barely heat up to 40 degrees. It takes 4 hours to take a shower (6 kilowatt hours of electricity). This does not include the fact that tap water temperatures are not high in winter. Swimming is more demanding. and heat consumption is high.
Now you can see that solar energy saves money!
It is also better to turn off the power supply when taking a shower, as solar heaters are easier to break and cause electric shock.
