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.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
