A hydraulic press is powered by a remote high-pressure pump. The gage pressure at the pump is $20 \mathrm{MPa}$, and the pressure required to operate the press is $19 \mathrm{MPa}$ (gage) at a flow rate of $0.032 \mathrm{~m}^{3} / \mathrm{min}$. The press and pump are to be connected by $50 \mathrm{~m}$ of drawn stainless steel tubing. The fluid properties are those of SAE 10 lube oil at $40^{\circ} \mathrm{C}$. What is the minimum tubing diameter that can be used?
