Consider the flow of engine oil at 10˚c in a 40-cm diameter pipeline at an average velocity of 0.5 m/s. a 1500-m long section of the pipeline passes through icy waters of a lake at 0˚c. disregarding the thermal resistance of the pipe material, determine (a) the temperature of the oil when the pipe leaves the lake (b) the rate of heat transfer from the oil and (c) the pressure losses in the pipe. assume the flow is hydro-dynamically fully developed.

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
