Propeller Flow - Momentum Equation

Consider a ducted propeller system, which is moving forward at a velocity V1. Analyse the system by assuming the duct remains stationary, as shown in the above diagram. If, for a specific design and point of operation V2/V1=9/4 and V1/V2=5/4... i) What is the thrust produced by the propeller in terms of the pressures at 2 and 3 and the area A?

Tank flow rate

With the valve closed, water flows from tank A to tank B as shown in attachment. What is the flow rate into tank B when the valve is opened to allow water to flow into tank C also? Neglect all minor losses and assume that the friction factor is 0.02 for all pipes.

Fluid Mechanics

Assume that the energy equation for a compressible gas can be written as:... Explain the meaning and units of the terms H,V,z,Q and W in this equation. (See attachment for the rest of the question)
