Unformatted text preview: and . ( ( b) Given )( . Assume that ) )( ) and , relate state 1 and state 2: The volumetric flow rate is determined by ̇ ̇ , (( )) ̇ 3) First applying mass conservation over the control volume from the piston to the exit ∯ (⃗ ⃗) Bernoulli’s equation may be used now to find the exit velocity, but first determine the pressure at the piston. Since the side of the piston on which the force is acting is open to ambient air, then the pressure is just the ambient pressure . The pressure on the other side of the piston is then a summation of the force and ambient pressures. 2/3 ( ( √ (( ) ) ) ) √ (( ( ) ) ) 4) Given Hydrostatics: , Assume ( ) , , and , Bernoulli’s Equation: , At maximum velocity , if submarine goes any faster there will be caviatation. () ( ) √ ( ) √ ( ) To go faster the subarine must increase depth: √ 3/3...
