An oil preheater consists of a single tube of 10 mm diameter and 5 m length, with its surface maintained at by swirling combustion gases. The engine oil (new) enters at 175˚C. What flow rate must be supplied to maintain an oil outlet temperature of 100˚C? What is the corresponding heat transfer rate?

A helix is made of 2-in schedule 40 pipe turned up to 21 giving a diameter of 1.5625 m. The liquid is entering through the coil at a temperature of 45 oC and leaving at 35oC. The average wall tube temperature is given to be 35oC. The volumetric flowrate of 2-propanol entering is .00279 m3 /s. Calculate the frictional pressure drop in a straight pipe and the pressure drop in coil. (Use equation 6-37 of Perry’s Handbook (9th edition) to calculate for fanning friction facto

QUESTION 3 A multi-stage steam turbine exhausts into a two-pass surface condenser operating at a pressure of 10kPa. The steam enters the condenser with a dryness fraction of 0.85 and the condensate leaves the condenser at a temperature of 34.6°C. The tubes have an inside diameter of 18mm and a wall thickness of 1mm. Coolina water circulates through the tubes at a speed of 1.2m/s. The stean flows through the condenser at a rate of 2400kg/hr and air leaks into the system at a rate of 0.5kg/1000kg of steam condensed. Calculate: 3.1 the capacity of the air pump in m2/min.
