Cold water with properties as shown in Table 4 flows at rate of
4 kg/s is heated from 28 oC to 54 oC in a shell-and-tube heat
exchanger as shown in Figure 4.The cold water inters the tubes
through thin-walled tubes, each tube has diameter of 19 mm, and the
average velocity inside each tube is 0.355 m /s. The shell side,
one pass is used with hot water as the heating fluid 1.8 kg/s

PROBLEM 3 (45 points) 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 parallel flow shell-and-tube heat exchanger consisting of a single shell and 1x10 tubes, each executing two passes. The inner diameter of tubes is D = 50 mm and its thickness is 5 mm (Do not ignore the thickness). The steam condenses on their outer surface. Thermal conductivity of the tube...

[20] Question 3 Crude oil is to be heated from 22 °C to 58 °C by heat exchange with the bottom product froma distillation column. The bottom product, flowing at 30 kg/s, is to be cooled from an initial temperature of 145 °C to 105 °C. The following shell and tube heat exchanger is available: 600 mm ID (1 shell pass) Shell inside diameter Tube configuration 2 passes 19.05 mm Tube outside diameter 2.1 mm Tube wall thickness 1.25 x...

a shell and tube heat exchanger is required to heat brine for a
food processing plant. Hot waste water from another part of the
plant is available at 90°C and a flow rate of 0.7kg/s to perform
the heating duty. An existing heat exchanger is available that has
twoshell passesand 4 tube passes. Each tube pass has a total length
of 20m and the tubes are found to be thin walled copper with a
nominal diameter of 25mm.

Problem 11.047 It is proposed that the exhaust gas from a natural gas-powered electric generation plant be used to generate steam in a shell-and-tube heat exchanger with one shell and one tube pass. The steel tubes have a thermal conductivity of 40 W/m.K, an inner diameter of 52 mm, and a wall thickness of 4 mm. The exhaust gas, whose flow rate is 2 kg/s enters the heat exchanger at 400°C and must leave...

Required information A shell-and-tube heat exchanger is used for cooling 47 kg/s of a process stream flowing through the tubes from 160°C to 136°C. This heat exchanger has a total of 100 identical tubes. each with an inside diameter of 2.5 cm and negligible wall thickness. The average properties of the process stream are: p = 950 kg/m”, k = 0.50 W/mK, Cp=3.5 kJ/kg.K, and -20 mPas The coolant stream is water (cp=4.18 kJ/kg K) at a flow rate of...

Water flowing at a rate of 10 kg/s through 50 tubes in a double-pass shell-and-tube heat exchanger heats air which flows on the shell side. The tubes are bras with outside diameter of 2.6 cm and are 6.7m long. The heat transfer coefficients on the inside and outside tube surfaces are 470 W/m2K and 210 W/m2K, respectively. Air enters the unit at 15°C with a flow rate of 16 kg/s. The entering water temperature is 350K. A) Draw and label...
