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 90Β° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90Β° 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.

Along steel shaft of 10 cm diameter is austenised at 870Β°c and then quenched in a liquid at 30oc. the average surface heat transfer coefficient is 2000 w/m2. Β°c. the relevant thermophysical properties of the shaft are: p=7800 kg/m", k=20 w/mk, cp=0.46 kj/kg.k calculate: a)-the time required for the center temperature to drop to 200Β°c. b)-the temperature at half-radius at that moment. c)-the amount of heat that had been transferred to the liquid by that time per meter length of the shaft
