6000 kg/h of steam at 10 bar and 4000C is expanded adiabatically to 0.5 bar in a turbine that generates power. The steam leaving the turbine is cooled by removing heat at the rate of 1.25 x 107kJ/h to produce saturated liquid at 0.5 bar. How much work is produced in the turbine (in kW)

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
