The 30 degree vertical bend in a pipe with a 2 ft diameter

carries water (rho = 62.4 lbm/ft^3) at a rate of 31.4 cfs. if the

pressure p1 is 10 psi at the lower end of the bend, where the

elevation is 100 ft, and p2 is 8.5 psi at the upper end, where the

elevation is 103 ft, what will be the vertical component of force

that must be exerted by the "anchor" on the bend to hold it in

position? the bend itself weighs 300 lb, and the length l is 4

ft.

Steam at a pressure of 100 kpa and a quality of 50% initially fills a rigid vessel having a volume of 0.5 m^3. the steam is then heated, causing the pressure in the vessel to rise to 150 kpa. determine: i. the mass of the steam in the vessel. ii. the temperature and quality of the steam after the heating process. ii the mass of the vapour, mg and liquid, m in the vessel after the heating process. if the steam in the vessel is now further heated, what would the pressure and temperature in the vessel be when all steam has turned into saturated vapour? b. sketch the processes in part (a) and part (b) on p-v and t-v diagrams, indicating clearly the temperatures, pressures and the paths. c. (0.59kg, 111.4°c, 73%, 0.4307kg, 0.1 593kg, 2.11 bar, 121.84°c)

Areheat rankine cycle operates with water as the working fluid. steam enters the first turbine at 8 mpa and 450°c and exits at 0.8 mpa. it is then reheated to 400°c before entering the second turbine, where it exits at 10 kpa. if the amount of work into the pump is 8.04 kj/kg and the net work per cycle produced is 1410.25 kj/kg, determine the thermal efficiency of the cycle.

At what temperature does the mole fraction of no reach 0.010 for the equilibrium products resulting from the combustion of gasoline and air at 1.0 and 5000 kpa?
