2. A fan is used to draw exhaust gases from a large hood. For highly turbulent flow, write an equation for the system which gives -M*r as a function of volume flow rate, Q. Neglect potential energy changes because a gas is being exhausted. For friction include only the contraction (e = 0.4), the expansion (e = 1.0) and the elbow (L/D : 20, f= 0.001). Note that -M*r has units of pressure and represents the "total pressure" against which the fan must operate. = ANSWER: (0.74 r /A2) Q2 Hood fan Area, A P= I atm Exit 1 atm
