Air at standard conditions enters the compressor shown in Fig. P5.26 at a rate of \(10 \mathrm{ft}^{3} / \mathrm{s}\). It leaves the tank through a 1.2-in.-diameter pipe with a density of \(0.0035 \mathrm{slugs} / \mathrm{ft}^{3}\) and a uniform speed of \(700 \mathrm{ft} / \mathrm{s}\).

(a) Determine the rate (slugs/s) at which the mass of air in the tank is increasing or decreasing.

(b) Determine the average time rate of change of air density within the tank.
