91. Which is the most suitable for cold viscous feed?
92. In a forward feed multiple effect evaporator unit
93. In a shell and tube type heat exchanger, the floating tube bundle heat arrangement is used
94. What is the unit of thermal conductivity?
95. Multiple effect evaporators are commonly used in the manufacture of P. Paper Q. Superphosphate R. Sugar S. Fats
96. Nusselt number is a function of Prandtl number and __________ number of fluid in natural convection heat transfer.
97. 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
98. The left face of a one dimensional slab of thickness 0.2 m is maintained at 80°C and the right face is exposed to air at 30°C. The thermal conductivity of the slab is 1.2 W/m.K and the heat transfer co-efficient from the right face is 10 W/m2.K. At steady state, the temperature of the right face in °C is
