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.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
