e. skisser temperaturpronien u varmt og kaldt vann som en funksjon av rørlengden Engelsk tekst A well-insulated double pipe heat exchanger (counter flow arrangement) is used to exchange heat between hot water and cold water. The tube side of the heat exchanger has an internal diameter of 0.05 m and wall thickness of 0.01m. The shell side of the heat exchanger has an internal diameter of 0.1 m. The hot water flows in the tube side with mass flow rates...

Question 5 - LMTD Heat Exchangers A 2 shell, 4 tube pass heat exchanger is being used to heat 50 kg/s of a process fluid in the tubes from an inlet temperature of 25°C to a target temperature of 80°C using condensing steam at 150°C. The overall heat transfer coefficient for a clean heat exchanger was U-1500W/m2.°C, however, the design engineer neglected to take into account fouling of the heat exchanger. After 5 years of use, fouling has occurred with...

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...
