Transcribed Image Text:
A single pass shell and tube heat exchanger, which uses the steam to heat 2.5 kg/s of water from 308 K to 358 K. Assume the steam enters at 473 K and leaves the heat exchanger at 378 K. Assume no phase change occur in either of the streams. Assume overall heat transfer co- efficient is U = 180 W/m²-K. Assume no radiation. a. Please draw a schematic of the heat exchanger and a temperature profile for both hot and cold streams b. Find heat transfer rate, q c. Using effectiveness-NTU method, find heat capacity ratio (C₁) and effectiveness (e) d. Calculate NTU of the heat exchanger e. Calculate the overall heat exchanger surface area. Properties: Water, liquid cp=4185 J/kg-K. A single pass shell and tube heat exchanger, which uses the steam to heat 2.5 kg/s of water from 308 K to 358 K.
