Ahigh-strength cast iron bar 5-in. in diameter is being turned on a lathe at a depth-of-cut da- 0.05-in. the lathe is equipped with a 15-hp motor and has a mechanical efficiency of 80%. the spindle speed is 500 rpm. estimate the maximum feed that can be used before the lathe begins to stall?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
