You are in alaska where it is cold; so you are pumping unused engine oil through a pre-heater in the shop before it flows into your equipment. the oil is flowing at a mass flow rate of 0.500 kg/sec through a 2.50 cm diameter tube (assume it is a "smooth tube") that is 20.0 m long. the inlet temperature of the oil is 10.0°c; and the constant surface temperature of the tube is 85.0°c.
1. calculate the following:
a) the outlet temperature of the oil.
b) the heat transfer rate.
c) the pumping power required.
d) provide comments (1-2 paragraphs) on the feasibility of doing this; would you recommend something to improve this process?
