Out of 100 kcal/second of incident radiant energy on the surface of a thermally transparent body, 300 kcal/second is reflected back. If the transmissivity of the body is 0.25, the emissivity of the surface will be

The purpose of providing a 'catchall' in the vapor line of an evaporator is to
-
What is the thermal conductivity of a perfect heat insulator ?
-
'Fouling factor' used in the design of a multipass shell and tube heat exchanger is a
