Three blocks A, B, and C and a grooved block D have dimensions a, b, c, and d as follows: a 1.500 ± 0.001 in h 2.000 ± 0.003 in c = 3.000 ± 0.004 in d = 6.520 ± 0.010 in 7 (a) Determine the mean gap w and its tolerance. (b) Determine the mean size of d that will assure that w 2 0.010 in.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

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
