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...

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 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...
