ith 3% moisture, 2.5 kg of steam has an enthalpy of 6600 kJ. It is heated at constant pressure to a final condition of 80 o Find (a) the pressure of the process, (b) the quantity of heat received by the steam, and (c) draw and use h-s diagram

For water at 100 kPa with a quality of 20%, find the volume fraction of vapor.

Find the quanity of heat required to produce 79% dry steam at 8000 kpa from feedwater at 50 degrees celcius ?.

A vessel of water containing 300 kg of water is initially at 270 K. A 100 kg piece of metal,initially at 1300 K, is placed in the water vessel to cool and the vessel is closed. The specificheat of the metal is 0.6 kJ/kg K and 4.2 kJ/kg K for water. Assume the specific heats areconstant and that the vessel is well insulated.a. Find the final equilibrium temperature after cooling. b. Find the amount of entropy generated within the vessel in kJ/K.

I need the answer as soon as possible

A rigid closed tank contains refrigerant 134a wnich is initally a two- phase liquid - vapor mxiure with a temperaflure of D'c and a quality of Ce0%. An electrical resistor nistalled inside the Fank transfers until the tank contains only saturated vapor. if the tank is well - insulated and the mass of the Cefrigerant is 1.5 kg, determıne the time it takes for the process to be completed in seconds using 5 signifigant Agures

Ammonia (an ideal gas) is contained in a 1.5 cubic meter pistion. Initially it is 200kPa 20C but it is compressed to 40C (at a constant pressurre). During this process, 1500kJ of heat is rejected to th 20C surrounding and 750 kJ of work is done. Is this process possible?

2) Two glass bulbs, one on the left with a volume of 2 liters and the other on the right with avolume of 6 liters, are connected to one another by a thin tube that is initially closed by astopcock. The bulb on the left has 0.1 moles of ideal gas, and the bulb on the right isevacuated. The system is in thermal equilibrium with the surroundings at 300K. When thestopcock is opened, the gas flows out to fill both bulbs. Calculate A for this process. If wewere to insert a propeller to extract work as the gas flows from left to right, what is themaximum amount of work that we could possibly extract?

Hi, pls help me solve this problem. Thank you so much.

6. Five pounds of a certain ideal gas with K 1.30 and R= 35 is compressed in %3D polytropic process in a closed system from 15 psia, 80 F to 60psia, 315 F. Compute the polytropic index n, the work nonflow and the heat interactions with the surroundings
