(4) A gear pump operating at 700 RPM has the following characteristics. \begin{tabular}{|r|r|r|r|} \hline \multicolumn{1}{|l|}{ viscosity, SSU } & capacity, gpm & BHP, hp & \multicolumn{2}{l|}{ EFFICIENCY, \% } \\ \hline 100 & 26 & 4.8 & 69 \\ \hline 10000 & 37 & 8.6 & 51 \\ \hline \end{tabular} (a) Determine the actual P s in psi of the fluids at the two viscosities. (b) If we assume the volumetric efficiency at 10000SSU is 99%, what is it at 100SSU ? (c) If there are 14 teeth in the gears, determine the displacement volume between 2 intermeshing gears, in in^ 3
