Aconverging elbow turns water through an angle of 135* in
avertical plane. the flow cross-sectional diameter is 400mm atthe
elbow inlet, section (1), and 200mm at the elbow outlet, section
(2). the elbow flow passage volume is0.2m3 between
sections (1) and (2). the watervolume flow rate is
0.4m3/s, and the elbow inlet andoutlet pressures are 150
and 90kpa. the elbow mass is12kg. calculate the horizontal (x
direction) and vertical (zdirection) anchoring forces required to
hold the elbow inplace.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

What precautions should you take to prevent injuries when dealing with heavy loads?

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?
