The total Tangential force on one ring of a Parson's Reaction turbine is 12000 N, when the blade speed is 100 m/s. the mass flow rate is 8 kg/s. the blade outlet angle is 20 degree. If the frictional losses occurred with pure impulse is 25 % of K. E. correspondence to relative velocity at entry of each ring of blade. the expansion losses are 20% of heat drop in the blade. What will be the absolute velocity of steam at exit?

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
