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.
