Several solar collectors are used to obtain energy from the sun to heat ethylene glycol. The ethylene glycol flows at 0.006 m3/s from the collectors to a plate and frame heat exchanger. The ethylene glycol enters the heat exchanger at 24°C, where it transfers heat to fresh water. The water enters the exchanger at 0.005 m3/s, with a temperature of 10°C. The plate height is 1.5 m, and a plate spacing of 4.3 mm. There are 15 plates made of...

A plate and frame HX has19 stainless steel (316SS) plates.9 m tall, 2 mm thick and .7 m wide which are spaced 5 mm apart. It is used to cool water at .012 m3/s,and inlet temperature of 35 C. The cooling medium s cold water which enters the HX at 7 C with the volumetric flow rate of 0.02 m3/s. What outlet temperature can be expected when the exchanger is new?

Q2. Shell-and-tube heat exchangers with hundreds of tubes housed in a shell are commonly used in practice for heat transfer between two fluids (shown in Figure 1). Such a heat exchanger used in an active solar hot-water system transfers heat from a water-antifreeze solution flowing through the shell and the solar collector to fresh water flowing through the tubes at an average temperature of 60°C at a rate of 15 L/S. The heat exchanger contains 80 brass tubes 1 cm...
