Determine the terminal settling velocity in water of a spherical sand particle of 0.5 mm diameter. the density of the sand is 2.65 x 10^3kg/m3, and the viscosity of water at 25 °c is 1.0 x lo^-3kg-m^-1.s^-1. hint: stokes' law is not appropriate.

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

When an object is heated it contracts. a. true b. false
