If I have a container with hot water coming in and mixed water exiting at the same flow rate, what is the energy balance for the system.
Tank
200 gal (0.76 m3)
k = 235 W/mk
surface area conducting heat = 4.98 m2
ambient air temp at 60F
because the water temperature varies coming into the tank, i calculated the heat transferred in instead. Assume constant at 148.4 kW.
8GPM (0.505 kg/s) into the tank
8GPM out of the tank
Tank water initially at 70F.
Please write the energy balance, or help me calculate a formula with the Tavg water in tank varied with time.
Thanks!
