Water flows at a rate of 0.035 m3 /s in a horizontal pipe whose diameter is reduced from 15 cm to 8 cm by a reducer. if the pressure at the centerline is measured to be 480 kpa and 445 kpa before and after the reducer, respectively, determine the irreversible head loss in the reducer. take the kinetic energy correction factors to be 1.05.

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
