An insulated rigid tank initially contains 1.4-kg saturated liquid water at 200°C and air. At this state, 25 percent of the volume is occupied by liquid water and the rest by air. Now an electric resistor placed in the tank is turned on, and the tank is observed to contain saturated water vapor after 20 min. Determine (a) the volume of the tank, (b) the final temperature, and (c) the electric power rating of the resistor.

3] Five kg of steam at 350 °c contains 15 % moisture. After addition of heat at constant temperature the pressure becomes 2.5 MPaa. Using steam tables, determine a) the steam initial pressure; b) the total heat added; c)the change in enthalpy; e) the change of internal energy; and d) the degrees of superheat at the final condition.
Define the low pressures (below the triplepoint value), solids evaporate without melting first (sublimation).
4. A 4 m storage tank is filled with steam and maintained at a constant temperature of 250°C. The initial pressure is 20 bar. A valve is opened and 1 kg/min of steam leaves the tank, What is the initial mass of the steam in the tank? How much time does it take for the pressure to decrease to 5 bar? [CO2]

hi, there experts. please help me with question 4. im having hard time answering it, please make your writings readable thank you! ^^
15. Statements Which of these statements are correct? (Note: multiple answers possible) U Water vaporizes at 100 [OC], it cannot evaporate into room air Water droplets can evaporate into air because of their low partial pressure Water droplets can evaporate into air because of their high partial pressure When spraying water droplets into air, the temperature of the air decreases The cooling effect of spraying droplets in very humid air (close to saturation) is much lower than spraying droplets in dry air Pump energy for spraying water is high and evaporative cooling is therefore not efficient
