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.
