A1/10th scale model of an airplane is to be tested in a wind tunnel that operates with air at a pressure of 20 atmospheres. the plane is expected to fly at a speed of 500 [km/hr]. (a) what speed should the wind tunnel be run? (b) if the drag measured on the model is 337.5 [n], what is the corresponding drag on the full size airplane? recall that the viscosity is effectively independent upon pressure changes.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
