Water is entering a storage tank at a temperature T0 and flow rate Q0 and leaving at a flow rate Q and temperature T. There are negligible heat losses in the tank. The area of cross-section of the tank is A0. The model that describes the dynamic variation of temperature of water in the tank with time is given as________________?
A Q0(T0 – T) = Ac . h (dT/dt)
B Q0T0 – QT = Ac . h (dT/dt)
C Q(T0 – T) = Ac . h (dT/dt)
D Q(T0 – T) = Ac . (dTH/dt)
Correct Answer: Q0(T0 – T) = Ac . h (dT/dt)
