A simple gas turbine system is to be modeled using a Brayton cycle. Air enters the compressor at 100 kPa and 300K. The compressor has a pressure ratio of 10 and an isentropic efficiency of 85% (ie. η.-0.85). Due to flow losses in the combustor the air enters the turbine at 950 kPa and 1400 K. The turbine has an exit pressure of i 00 kPa and an isentropic efficiency of 88% (ie, 0.88). Assume constant specific heats. (i. e. Cv 0.717 kJ/kgK, Cp- 1.004 kJ/kgK).

a) Sketch the T-s diagram for the entire system including both the isentropic and actual states
b. for the compressor and turbine. Label the states.
c. Find the actual compressor work (kJ/kg).
d. Find the actual turbine work (kJ/kg) Find the heat transfer into the combustor (kJ/kg)

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
