Please Answer
Steam enters a nozzle at 400°C and 800 kPa with a velocity of 10 m/s and leaves at 375°C and 400 kPa while losing heat at a rate of 26.5 kW. For an inlet area of 800 cm², determine the velocity and the volume flow rate of the steam at the nozzle exit. Use steam tables.

The velocity of the steam at the nozzle exit is m/s.

The volume flow rate of the steam at the nozzle exit is m³/s.

Required information A gas is compressed from an initial volume of 0.42 m³ to a final volume of 0.12 m³. During the quasi-equilibrium process, the pressure changes with volume according to the relation P= aV+b, where a = - 1200 kPa/m³ and b= 1000 kPa. Gas P = a + b Calculate the work done during this process by performing the necessary integration. (Include a minus sign if necessary.) The work done is kJ.
You are replacing an HVAC system in your building. The system is a steam system that consists of a boiler that feeds several air-handling units.

It is a hot day in Atlanta and you and your friends bought an ice cream maker. The unit consists of a bowl and a base that rotates the bowl around a stationary mixing paddle. The walls of the bowl contain an unknown mixture that absorbs heat from the ice cream. The bowl must be frozen (-20°C) before use. Unfortunately, your friends have lost the instructions and can't remember how long to operate the unit. You tell them not to worry since you have mastered energy conservation problems and can calculate the amount of time required to freeze the ice cream. Looking at the box, you find the specifications for the unit: a) Inner surface area of freezing bowl: 600 cm2; b) Heat transfer coefficient for bowl:h = 0.025 J / (cm2 s .°C); c) Power required to stir the bowl (100% efficiency):25 W; d) Amount of ice cream mixture added: 1 kg; e) The rate of heat transfer is between the bowl and the milk. You know that solutes lower the freezing point of water. Assume that the freezing point is…
