Which of these parameters in quasi – one dimensional flow varies w.r.t. x as opposed to the one – dimensional flow?

Which of these parameters in quasi – one dimensional flow varies w.r.t. x as opposed to the one – dimensional flow? Correct Answer Cross – sectional area

One – dimensional flows are those flows that have a constant crossectional area and only the flow variables i.e. pressure, velocity, density, temperature etc vary wrt x. What separates Quasi one – dimensional flow from this is the variable cross – sectional area wrt x.

The important parameters describing the performance of a hydraulic machine are: P the power input, H the head produced across the machine and the efficiency, η. For a given geometrical design of the machine, the performance is characterized by the variables: H – the head increase across the machine ρ – the fluid density, ω – the angular velocity of the rotor, D – the diameter of the rotor, μ  – the fluid viscosity and Q – the flow rate; and both P and η are expressed through these variables.
