In a hydroelectric power plant, water enters the turbine nozzles at 820 kpa absolute with a low velocity. if the nozzle outlets are exposed to atmospheric pressure of 100 kpa, determine the maximum velocity to which water can be accelerated by the nozzles before striking the turbine blades.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
