8. Water flows through a horizontal 150 mm diameter pipe under a pressure of 414 kPa. Assuming no losses, what is the flow rate, Q, if the pressure at a 75mm diameter reduction is 138 kPa. Ans. 0.11 m3/s.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.
