Saturated, pure steam at a temperature of 170 oC condenses on the outer surface of a vertical tube of outer diameter 2 cm and length 1.5 m. The tube surface is maintained at a uniform temperature of 150 oC.
Calculate:
the local film condensation heat-transfer coefficient at the bottom of the tube.
the average condensation heat-transfer coefficient over the entire length of the tube.
the total condensation rate at the tube surface.

AH of vaporization of water is 439.2 cal/g at the normal boing point. Since virus can survive at 404.39 K by forming
spores. Most virus spores die at 851.9 K. Hence, autoclaves used to sterilize medical and laboratory instruments are
pressurized to raise the boiling point of water to 851.9 K. Find out at what InP (torr) does water boil at 851.9 K?

Provide operating temperatures and pressures entering each component shown in the diagram (at points 1, 2, 3, 4). Indicate which chiller should be chosen based on the economics. See below for details: -Your work is replacing a chiller that is used as part of a distillation process that condenses methanol (boiling point = 65 °C). Your task is to select the most economical type of system. A conventional chiller will have a lower first cost and will have lower maintenance costs than one that involves enhanced heat transfer surfaces, but the chiller with enhanced surfaces will condense the same amount of alcohol with a lower energy consumption. Select the appropriate chiller by considering the net present value of both systems. That value will involve the first cost of the chiller, and the present value of the maintenance and energy costs. The chiller uses a standard vapor-compression refrigeration cycle with R-22 (see Figure 1). For…arrow_forward
