plz help for a thumbs up

E. A counter flowing heat exchanger (s. Fig. E) for cooling a hot hydrocarbon liquid at atmospheric pressure uses mc = 5 kg/s of cooling water, which enters the heat exchanger at 20 C. The average heat capacity of the water is Cp,c = 4.18 kJ/kg K. The mass flow rate of the hydrocarbon is min = c 10 kg/s, its average heat capacity is Cp,h3.2 kJ/kg K, its temperature at the inlet of the heat exchanger is 325 C and at the exit 175 C. = E E min, Tin nin, Tan Direction of heat transfer HEAT EXCHANGER nic Tac nic, Tic T Tih Tac Tan Tic
