Heat Transfer One kilogram of water at 0°C is changed to superheated steam of one atm pressure and 300° C. The major heat consumption in the process will be to Heat the water from 0°C to 100°C Evaporate the water To superheat the steam Data insufficient, can Heat the water from 0°C to 100°C Evaporate the water To superheat the steam Data insufficient, can ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient Should not be used as it gives very high pressure drop Flows through the tube Flows outside the tubes Can flow either inside or outside the tubes Should not be used as it gives very high pressure drop Flows through the tube Flows outside the tubes Can flow either inside or outside the tubes ANSWER DOWNLOAD EXAMIANS APP

Heat Transfer A composite wall consists of two plates A and B placed in series normal to the flow of heat. The thermal conductivities are kA and kB and the specific heat capacities are CPA and CPB for plates A and B respectively. Plate B has twice the thickness of plate A. At steady state, the temperature difference across plate A is greater than that across plate B, when KA < 0.5kB CPA < CPB CPA > CPB KA>2 kB KA < 0.5kB CPA < CPB CPA > CPB KA>2 kB ANSWER DOWNLOAD EXAMIANS APP
