Question: An engineering student plans to perform a hover show using a fan. The student thinks that he can achieve this if he arranges a fan

An engineering student plans to perform a hover show using a fan. The student thinks that he can achieve this if he arranges a fan with a blade diameter of 91.5cm, which he will place in a case, 10 send the air downwards. The fan can rotate at 600 revolutions per minute. The weight of the system is 22.27N, and by increasing the student's power, the student plans to increase the rotational speed of the wings and thus the airspeed until it provides the thrust to lift the chassis off the ground. Determine (a) the volumetric flow required for this and (c) the required minimum power. The density of the air can be taken as 1.25kg/m3
