A90 mm diameter cylindrical part is turned on a lathe at 600 rpm. if the depth of cut is 5 mm, feed rate is 0.2 mm/rev, and specific energy of the workpiece material is 3.5 w? s/mm3, calculate the minimum power of the lathe.

The temperature of air decreases as it is compressed by an adiabatic compressor. 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.

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?
