In a parallel flow heat exchanger operating under a steady state, the heat capacity rates (product of specific heat at constant pressure and mass flow rate) of the hot and cold fluid are equal. The hot fluid, flowing at 1 kg/s with sp. heat = 4 kJ/kg.K, enters the heat exchanger at 102 C while the c

In a heat exchanger, it is observed that ΔT1=ΔT2, where ΔT1 is the temperature difference between the two single-phase fluid streams at one end and ΔT2 is the temperature difference at the other end. This heat exchanger is A. a condenser B. an evaporator C. a counter flow heat exchanger D. a parall

In a certain double pipe heat exchanger, hot water flows at a rate of 50,000 kg/h and gets cooled from 95 C to 65 C. At the same time 50,000 kg/h of cooling water at 30 C enters the heat exchanger. The flow conditions are such that the overall heat transfer coefficient remains constant at 2270 W/m^2

Air enters a counter-flow heat exchanger at 70 C and leaves at 40 C. Water enters at 30 C and leaves at 50 C. The LMTD in deg C is _______ A. 5.65 B. 14.43 C. 19.52 D. 20.17

In a concentric counter flow heat exchanger, water flows through the inner tube at 25 C and leaves at 42 C. The engine oil enters at 100 C and flows in the annular flow passage. The exit temperature of the engine oil is 50 C. The mass flow rate of water and the engine oil are 1.5 kg/s and 1 kg/s, re
