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

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
