In the final stages of production, a pharmaceutical is sterilized by heating it from 25 to 75°C as it moves at 0.22 m/s through a straight thin-walled stainless steel tube of 12.7-mm diameter. A uniform heat flux is maintained by an electric resistance heater wrapped around the outer surface of the tube. If the tube is 10 m long, what is the required heat flux? If fluid enters the tube with a fully developed velocity profile and a uniform temperature...

A shell and tube heat exchanger with one shell pass and two tube passes is used to heat 8.82 kg/s of fluid from 15.6 °C to 60 °C by using saturated steam at 150 kPa. The steam is condensing on the outside of the tubes with h= 15 kW/m2.K. There are 50 tubes with an outside diameter of 1.91 cm and a wall thickness of 0.211 cm. If the fouling coefficient on the inside of the tubes is 5678 W/m2.K,...

[10] Design Problem As shown in the figure below, a double-pipe parallel-flow heat exchanger is used to heat cold fluid which is water (Cp = 4180 J/(kg.K), p = 1000 kg/m) from 20°C to 80°C at a rate of 0.15 kg/s. The heating is to be accomplished by hot fluid, which is geothermal water (Cp = 4310 J/(kg.K), p = 1050 kg/m²) available at 130°C at a mass flow rate of 0.25 kg/s. The inner tube has an inner diameter...

The condenser of a large steam power plant is a heat exchanger in which steam is condensed to liquid water. Assume the condenser to be a shell-and-tube heat exchanger consisting of a single shell and 30,000 tubes, each executing two passes (see figure below). The tubes are of thin wall construction with D=25mm, and steam condenses on their outer surface with an associated convection coefficient ho=11,000W/ m K The heat transfer rate that must be effected by the heat exchanger...

2. (10 points) A pharmaceutical fluid is sterilized by heating it from 25 to 75 °C as it moves at 0.2 m/s through a straight thin-walled stainless steel tube of 12.7-mm diameter that is 10 m long. A uniform heat flux is maintained by an electric resistance heater wrapped around the outer surface of the straight tube. The pharmaceutical fluid properties may be approximated as: p = 1000 kg/mº, cp = 4 kJ/kg-K, u = 2.102 kg/s-m, k = 1...

A counter-flow heat exchanger is stated to have an overall heat transfer coefficient of 284 W/m2.K when operating at design and clean conditions. Hot fluid enters the tube side at 101°C and exits at 71°C, while cold fluid enters the shell side at 27°C and exits at 42°C. After a period of use, built-up scale in the heat exchanger gives a fouling factor of 0.0004 m2 K/W. The surface area is 93 m². Assume both hot and cold fluids have...

Problem 3. (25 points) In a Rankine power system, 1.5 kg/s of steam leaves the turbine as saturated vapor at 0.51 bar. The steam is condensed to saturated liquid by passing it over the tubes of a shell-and-tube heat exchanger, while liquid water, having an inlet temperature of T = 280 K, is passed through the tubes. The condenser contains 100 thin-walled tubes, each of 10-mm diameter, and the total water flow rate through the tubes is 15 kg/s. The...
