Liquid ethanol with a density of 49.3 lbm/ft3 flows through a nozzle. At the inlet of the nozzle, the ethanol has a velocity of 10 ft/s, and the velocity of the ethanol at the outlet is 110 ft/s. The cross-sectional area of the outlet is 0.0075 ft2.
(a) Determine the cross-sectional area of the outlet, assuming that the nozzle operates at steady-state, steady-flow conditions. (b) Using your equations, for a constant outlet condition, plot the cross-sectional area of the nozzle inlet as the inlet velocity varies from 2 ft/s to 100 ft/s. Given: p= 49.3 lbm/ft3; V1 = 10.0 ft/s; V2 = 110 ft/s; A2 = 0.0075 ft2 What will be an ideal response?What will be an ideal response?
