Question: The following handbook data are available for hydraulic hose. The fluid has a specific gravity Sg= 0.868 and viscosity ν = 20.6 cS.

Note: The velocities are slightly higher than the 15 ft/s recommended for pressure lines. The fluid velocity is approximately equal, because size (ID) increases as flow increases. However, the pressure drop decreases as ID increases.

1. Derive the table values using the equations. You may use a friction factor given in Fig. for the elastomer inner tube of the hydraulic hose.

2. Suppose viscosity doubles to ν = 43.3 cS. What influence will this have on pressure drop? Report your result for the 10 GPM flow only.
