Ashell-and-tube heat exchanger with two tube passes is to heat 20,000 kg/h of water from 25 to 84oc by hot engine oil flowing through the shell. the oil makes a single shell pass, entering at 160oc and leaving at 94 oc, with a heat transfer coefficient of 500 w/m2×k. the heat exchanger contains 100 steel tubes of 22.9-mm inside diameter and 25.4-mm outside diameter. the inside heat transfer coefficient is 3210 w/m2×k. neglecting fouling coefficients, determine the required tube length.

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
