HW #3, Fall’07 BEE 331 Bio-Fluid Mechanics HW #3 1. Find the position and magnitude of the resultant force on this vertical wall of a tank which has oil, of relative density 0.8, floating on water as shown. 2. A mercury manometer is used to measure the pressure difference in the two piplines of the figure shown. Fuel oil ( γ = 53.0 lb/ft 3 ) is flowing in A and SAE 30 lube oil ( = 57.0 lb/ft 3 ) is flowing in B. An air pocket has become entrapped in the lube oil as indicated. Determine the pressure in pipe B if the pressure in A is 15.3 psi. (Unit weight of water = 62.4 lb/ft 3 ). 3 . Sleep apnea is a disorder involving brief interruptions of breathing during sleep. Many patients who suffer from sleep apnea can benefit from devices that maintain a continuous positive airway pressure in their trachea. Part of this device contains a pressure sensor that can be used to monitor pressure during sleep. Since pressure changes are small, an inclined manometer is used. Determine the maximum angle
