SAE 50 oil flows at a mass flow rate of 0.007 kg/s through a 1-cm I. D. tube that is 1.5 m long. The wall temperature is at 300 K and the inlet oil temperature is 377 K. Calculate: (1) The average heat transfer coefficient, (2) the oil temperature at the outlet, and (3) the convective heat loss from the oil

A5 kg block of fe is dropped into a very large vat of water. the fe and water initial temperatures are 95 and 25 c, respectively. the fe final temperature is 25 c and the water can be treated as a thermal reservoir,. treated as a thermal reservoir take the water to be the system and determine the entropy generation. report vour answer in kj/k.
