Repeat Problem 3.54 for air flowing radially inward.

Problem 3.54

Air flows radially outward between the two parallel circular plates shown in Fig. P3.54. The pressure at the outer radius \(R_{o}=\) \(5.0 \mathrm{~cm}\) is atmospheric. Find the pressure at the inner radius \(R_{i}=\) \(0.5 \mathrm{~cm}\) if the air density is constant, the air flow is inviscid, the volume flow rate is \(4.0 \mathrm{~L} / \mathrm{s}\), and the plate spacing is \(h=0.125 \mathrm{~cm}\).
