V Show your work. a) A physical quantity is dened as follows Q = 33%, where Q and b are both measured in lbf per square inch, and a is measured in lbf per cubic foot. To keep the equation dimensionally homogeneous, what are the units (if any) of the constant 33? b) Fun with unit conversions. A toy plastic boat has a mass of 625 grams and a volume of 0.27 cubic feet. Determine the density of the plastic in chips per munk, given 1 chip = 12.5 kg and 1 munk = 8 liters. 0) Pressure loss due to pipe friction can be computed by the formula Ap = 2 f L p v2 / d where Ap = pressure loss (Pa) (1 = pipe diameter (m) f = friction factor (dimensionless) p = uid density (kg/m3) L = pipe length (m) v = uid velocity (m/s) Find Ap (Pa) for d = 3 in, f= 0.02, p = 1.1 g/cm3, L = 25 ft, and v = 215 ft/min
