Water is the working fluid in a rankine cycle. superheated vapor enters the turbine at 10 mpa, 480°c, and the condenser pressure is 6 kpa. the turbine and pump have isentropic efficiencies of 80 and 70%, respectively. determine for the cycle(a) the heat transfer to the working fluid passing through the steam generator, in kj per kg of steam flowing.(b) the thermal efficiency.(c) the heat transfer from the working fluid passing through the condenser to the cooling water, in kj per kg of steam flowing.

Ahonda civic travels in a straight line along a road. its distance x from a stop sign is given as a function of time t by the equation x(t)= î± t2â î² t3, where î± = 1.53 m/s2 and î² = 5.50ã10â2 m/s3 .

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
