The following data refer to a compound impulse turbine having two rows of moving blades and one row of fixed blades in between them.

Nozzle angle \(=15^{\circ}\), Exit velocity of steam from the nozzle \(=450 \mathrm{~m} / \mathrm{s}\)

Moving blades tip discharge angles \(=30^{\circ}\)

Fixed blade discharge angle \(=20^{\circ}\)

Friction loss in each blade rows \(=10 \%\) of the relative velocity Calculate the blade velocity, blade efficiency and specific steam consumption for the turbine.
