QI: Determine the percentage increase in efficiency of an Atkinson cycle in comparison with the otto cycle for a compression ratio of 8.5. The pressure and
temperature of air at the beginning of compression are 1 bar and 27 °C
respectively. The peak pressure is 45 bar for both cycles.

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
