Apropeller of 75mm diameter installed in a 150mm pipe carrying water at 42.5 l/s is found to rotate at 20.7rps. if a geometrically similar propeller of 375mm diameter rotates at 3rps in air flow through a pipe of 750mm diameter, estimate the volume flow rate of the air. comment on whether this estimate is reliable, giving reasons for your answer.
