Assuming Stokes behavior, calculate the terminal settling velocity in standard air () for the following particles: (a) diameter = 25 μm, specific gravity = 1.9; (b) diameter = 2.5 μm, specific gravity = 0.8; and (c) diameter = 45 μm, specific gravity = 2.6

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Compute the pressure drop of 30°c air flowing with a mean velocity of 8 m/s in a circular sheet-metal duct 300 mm in diameter and 15 m long. use a friction factor, f 0.02, and pair = 1.1644 kg/m a. 37.26 pa b. 25.27 pa n c. 29.34 pa d. 30.52 pa

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
