A half body is formed by the superposition of a uniform flow and a source. Consider the superposition of a uniform flow with a velocity of 300 ft/s and a source placed at the origin with a strength of 100 ft2/s. What is the gage pressure at a point located at θ=80o, r = 0.3 ft? The pressure upstream is the atmospheric pressure and the density of the fluid is rho=0.00235 slug/ft3.

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

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.
