Unformatted text preview: pressure. This is seen in the function of power consumption where delta p and flow rate Picture 1 are direct variables. Ideally the best design would be to have a large plenum with the least possible mass. 2. The mentioned fan, would not fit the design of this circular hovercraft, because the performance point lies beyond that of the pressure vs air flow curve of this motor. Reasoning: p=1.5(9.81)/(pi(.67/2)^2)= 41.76 pa Q=(60*(2 p(lh)^2)/1.2)^.5=2.1m^3/min performance point 3 a. Q=1.2 p=13 pa V= Q/A= 1.2/60/(pi .046^2)= 3.01m/s T= pA= 13(pi.046^2)= .0864N pQ= 13*1.2/60 = .26 nm/s*.25= .065W...
