Tests done on a scale model of a turbine diameter 0.3m gave a max. efficiency of 83% at 900rev/minute with a guide vanes 75% open and pressure head of 20m. The power developed was 28.5KW A geometrically similar turbine has to produce 375kW at 75% vane opening but under a head of 26m Calculate 1) the diameter 2)the rotational speed of the full scale turbine hint assume the efficiencies of both machines to be the same

A model of a Francis turbine is built to a scale of one fifth of full size and when tested it developed a power output of $3 \mathrm{~kW}$ under a head of $1.8 \mathrm{~m}$ of water, at a rotational speed of $360 \mathrm{rev} / \mathrm{min}$ and a flow rate of $0.215 \mathrm{~m}^3 / \mathrm{s}$.Estimate the speed, flow rate, and power of the full-scale turbine when working under dynamically similar conditions with a head of $60 \mathrm{~m}$ of water. By making...
