1. The pressure gauge on a 20-ft tank of nitrogen at 75 F reads 82 psi. Estimate the mass (lbm) of nitrogen in the tank by: (a) direct solution of the ideal gas law, and (b) conversion from standard conditions. (See Table 5.1 in the Course Notes.) You must work the problem in the given units (i.e., American Engineering system of units). Do not convert to the SI or any other system of units. Table 5.1.
