A two-shell-four-tube-pass heat exchanger has an overall heat exchanger conductance of 350 W/m^2?K and is used to cool 10 kg/s of engine oil from 180ºC to 80ºC. If water at 20ºC is used to cool the oil and the water temperature leaving the heat exchanger is 60ºC, determine (a) mass flow of water required and (b) surface area of the heat exchanger.

A bucket of water with total mass 23 kg is attached to a rope, which in turn is wound around a 0.050-m radius cylinder, with crank, at the top of a well. The moment of inertia of the cylinder and crank is 0.21 kgm2 . The bucket is raised to the top of the well and released to fall back into the well. What is the kinetic energy of the cylinder and crank at the instant the bucket is moving with a
speed of 6.0 m/s? a. 2.1 × 10^3 J c. 0.86 × 10^3 J b. 1.5 × 10^3 J d. 0.40 × 10^3 J
