A single row impulse turbine develops $130 \mathrm{~kW}$ at a blade speed of $180 \mathrm{~m} / \mathrm{s}$ using $2 \mathrm{~kg} / \mathrm{s}$ of steam. The steam leaves the nozzle at $400 \mathrm{~m} / \mathrm{s}$. The friction coefficient for blades is 0.9 and steam leaves the blades axially. Determine

(a) nozzle angle, and

(b) blade angles at entry and exit, assuming no shock.
