A typical UK domestic hot water tank holds c. 200 litres of water. Hitherto the common method of heating it to say 60C has been by means of an internal coil of copper pipe through which is pumped hot water from a gas boiler at ~ 70C. Heat transfer on the outside of the coil is by natural...
I draw this diagram:
The formula for hydrostatic pressure is: ##P=\rho g h## so I just plug everything
$$P=1000 \times 9.8 \times 0.1=980 Pa$$

This is a past exam paper Q.
I think i might be missing info though.
For i) i use q=UAdT

dT= (80-20)
They haven't given U but if i know answer should be 1,050W
So if i set U to 0.5

= 1050W
Am i missing something or could I calculate U with the info given?

Hi,
If it is assumed the temperature of a shower is to be 43°C and the electric shower consumes 50 litres of water at that temperature, then the Energy required for an electric shower would be:

QElectric Shower = 6.89945 kJ or...
Based on my understanding,
Top Tank Refilling
Advantage: Atmospheric Pressure
Disadvantage: High Head (Requires more distance, thus more Work since W = f x d)
Bottom Tank Refilling
Advantage: Low Head
Disadvantage: High Static Pressure (Requires more Force, thus more Work since W = f x d)...
