A heat exchanger with one body and eight pipe passesis designed. Water flows from the exhaust gas pipes as cold fluidby the body as cold fluid. Exhaust gas to the system at 210 °C
and entering at a temperature of 140 ° C
The heat transfer coefficient is 392 W / m2K. On the other hand,water enters 16 iron (k = 38 W / mK) pipes with an inner diameterand outer diameter of 32 mm and 36 mm, respectively, at atemperature of 600 cm / s at 40 ° C and exiting at a temperature of80 ° C. According to this
a.) Find the flow rate of the exhaust gas.
b.) Find the total heat transfer area.
c.) Calculate the pipe length for one pass.
(The properties of the water will be taken from the table. The airtable will be used for the exhaust gas.)
