An air compressor increases the pressure (Pout > Pin) and the density (?out > ?in) of the air passing through it. For the case in which the outlet and inlet diameters are equal (Dout = Din), how does average air speed change across the compressor? In particular, is Vout less than, equal to, or greater than Vin? Explain.
A Francis radial-flow hydroturbine is being designed with the following dimensions: r2 = 2.00 m, r1 = 1.42 m, b2 = 0.731 m, and b1 = 2.20 m. The runner rotates at n. = 180 rpm. The wicket gates turn the flow by angle ?2 = 30° from radial at the runner inlet, and the flow at the runner outlet is at angle ?1 = 10° from radial. The volume flow rate at design conditions is 340 m3 /s, and the gross head provided by the dam is Hgross = 90.0 m. For the preliminary design, irreversible losses are neglected. Calculate the turbine specific speed of the turbine. Provide answers in both dimensionless form and in customary U.S. units. Is it in the normal range for a Francis turbine? If not, what type of turbine would be more appropriate?
