What is the difference between co-current heat exchanger and counter-current heat exchanger? A. Counter-current heat exchanger is smaller in size compared to co-current heat exchanger B. Counter-current heat exchanger has baffles in the shell side where as co-current heat exchanger does not has any baffle C. Counter-current heat exchanger can produce better temperature control compared to co-current heat exchanger D. Counter-current heat exchanger can have cross-temperature between fluid in and fluid out where as co-current cannot have cross-temperature During the cooling tower experiment, the changes in air temperature in and out of the cooling tower were significant. However, the temperature change for water is very small. Why there is a difference between both of the fluid? A. Both fluid has a different calorific values B. The area for heat transfer is not large enough to transfer the heat C. Water did not flow consistently at all area in the cooling tower D. The temperature of water entering the cooling tower was too low Estimate the heat loss per square metre of surface through a brick wall 0.5 m thick when the inner surface is at 400 K and the outside surface is at 300 K. the thermal conductivity of the brick may be taken as 0.7 W/mK A. 100 W/m2 B. 104 W/m2 C. 1.34 kW/m2 D. 1.40 kW/m2
