Is there any good videos out there that could help explained how to do these math questions ?

do you guys know of a good place to get used text books? like asme b31.1 and asme b 31.3? or where the best place is to get new ones?

having trouble with this question a single stage impulse turbine has blades with inlet and outlet angles of 35 deg. the mean blade diameter is 600 mm and the turbine runs at 6000 r/min. the steam leaves the rotor in the axial direction ( 90 deg to blade direction ). ignoring the effects of friction, determine a) nozzle angle b) the velocity of steam leaving the nozzle c) the power developed, per kilogram of steam flow
