ChE 2114 First Quiz August 31, 2007 g = 9.81 m/s 2 or 32.2 ft/s 2 1. (30 points) What is the mass (in pounds mass) of an object that will accelerate at 1.00 ft/s 2 when subjected to a force of 1.00 pound force? 2. (30 points) The Prandtl Number, N Pr , is a dimensionless group important in heat transfer calculations. It is defined as N Pr = C p μ /k, where C p is the heat capacity of the fluid,

Unformatted text preview: μ is viscosity, and k is thermal conductivity. For a particular fluid, C p = 0.583 kJ/(kg)( o C) μ = 2.88x10 4 g/(cm)(hour) k = 0.286 watt/(m)( o C) Calculate the numerical value of the Prandtl Number. 3. (40 points) What is the gauge pressure, in pounds per square inch gauge, at the bottom of a 450 centimeter column of a liquid with SG = 1.60 20/4?...
