The death rate an airbag vehicles is how much greater than that of those with no airbags

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

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

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
