Problem 1: This is textbook problem 4.51 (page 224) Steam at 1800 lbf/in2 and 1100 °F enters a turbine operating at steady state. As shown in the Figure, 20% of the entering mass flow is extracted at 600 lbf/in2 and 500 °F. The rest of the steam exits as a saturated vapor at 1 lbf/in2 . The turbine develops a power output of 6.8×106 Btu/h. Heat transfer from the turbine to the surroundings occurs at a rate of 5×104 Btu/h....

******ONLY MATLAB CODE NO OTHER WAY OF SOLUTION****** Consider a one-dimensional slab with conductivity 1 W/m-K. The slab width is 20 cm. The left face of the slab is at 100oC and the heat flux at the right face is 1 kW/m2. The slab experiences a volumetric heat generation rate given by S = 1000 - 5T W/m3. Determine the steady-state temperature distribution in the slab, for two grid spacings with the requirement that there should be at least 20...

What is wrong with the following proof by induction that this statement is true for all n? Certainly P is true. Now assume that Pr is true, and take any group of n+1 persons containing at least one male. Let G pI,p2sp3,..Pa Prt denote this group, with pi being the known male. The subgroup (pi,p2,p3,... n) of G...
