A 16-mm diameter copper rod is 5/8 in long and has an allowable stress of 15 ksi. Determine how much the rod must be stretched to develop this allowable stress. Recall that = PL AE

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

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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.
