$1.$ A single row, impulse turbine has blade whose inlet angle is $40$ and exit angle is

$37.$ The mean blade speed is $230$ m$/$s and the nozzles are inclined at an angle $27$

to the plane of rotation of the blades. There is a $10\%$ loss of relative velocity due

to friction in the blades. The turbine uses $550$ kg$/$h of steam.

Determine:

$($a$)$ the nozzle velocity of the steam;

$($b$)$ the absolute velocity of the steam at exit;

$($c$)$ the power output of the turbine;

$($d$)$ the end thrust on the turbine;

$($e$)$ the diagram efficiency.A single row, impulse turbine has blade whose inlet angle is $40$ and exit angle is
