1. A cylindrical container with a height of 5 inches and a diamter of 4 inches is filled completely with a fluid weighing 500g. What is the density of the fluid in kg/cm3 , lbm/ft3 , and g/mL? the answer must be: 4.9*104 kg/cm3 = 30.3 lbm/ft3 = 0.49 g/mL

2. The gauge on a nitrogen cylinder in the lab reads 500 psi. What is the absolute pressure? Give your answer in psia, kPa, bars, and atm. The answer must be: 514.7 psia = 3,536 kPa = 35.36 bars = 35.01 atm

Solution

volume =pi*r^2*h.

volume=3.14*12.7*5.08*5.08=1029.6296ml

density=mass/volume

density=500/(1029.6296 ) =0.4856g/cm3
