Heat Transfer Three solid objects of the same material and of equal mass-a sphere, a cylinder (length = diameter) and a cube are at 500°C initially. These are dropped in a quenching bath containing a large volume of cooling oil each attaining the bath temperature eventually. The time required for 90% change in temperature is the smallest for Equal for all the three Cube Sphere Cylinder Equal for all the three Cube Sphere Cylinder ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer The advantage of using a 1 - 2 shell and tube heat exchanger over a 1 - 1 shell and tube heat exchanger is Lower shell side pressure drop Lower tube side pressure drop Higher tube side heat transfer co-efficient Higher shell side heat transfer co-efficient Lower shell side pressure drop Lower tube side pressure drop Higher tube side heat transfer co-efficient Higher shell side heat transfer co-efficient ANSWER DOWNLOAD EXAMIANS APP
