A large mass is supported by a piston of diameter \(D=4 \mathrm{in}\). and length \(L=4\) in. The piston sits in a cylinder closed at the bottom, and the gap \(a=0.001 \mathrm{in}\). between the cylinder wall and piston is filled with SAE 10 oil at \(68^{\circ} \mathrm{F}\). The piston slowly sinks due to the mass, and oil is forced out at a rate of \(0.1 \mathrm{gpm}\). What is the mass (slugs)?
