Water is entering a storage tank at a temperature T0 and flow rate Q0

1.	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)
Answer» B. Q0T0 – QT = Ac . h (dT/dt)
