Apressurized 2-m-diameter tank of water has a 10-cm-diameter orifice at the bottom where water discharges to the atmosphere. the water level initially is 3 m above the outlet. the tank air pressure above the water level is maintained at 450 kpa absolute and the atmospheric pressure is 100 kpa neglecting frictional effects, determine: (a) how long it will take for half of the water in the tank to be discharged; (b) the water level in the tank after 10 s

Fluids at rest possess no flow energy. a)- true b)- false

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
