Chemical Engineering :: Heat Transfer
-
In a heat exchanger with steam outside the tubes, a liquid gets heated to 45°C, when its flow velocity in the tubes is 2 m/s. If the flow velocity is reduced to 1 m/s, other things remaining the same, the temperature of the exit liquid will be
-
For a liquid in laminar flow through a very long tube, when the exit fluid temperature approaches the wall temperature, the equation to be used is
-
Multiple effect evaporation accounts for
-
In case of a supercooled solution, which is on the verge of crystallisation, the free energy of the solution as compared to that of the solid is

Which of the following is the most widely used heat insulating material for pipelines carrying steam ?
-
Heat transfer co-efficient equation for forced convection, Nu = 0.023 Re0.8 . Prn, is not valid, if the value of
