Container is filled with water. The total volume is 5 m^3. 1% of the volume is saturated liquid and 99% of the volume is saturated steam where the pressure is 0.1 MPa within the container. Heat is transported to the container until all the water turns into saturated steam. Find how much heat is required for the process to occur.

Take a correct Value of R. Don't waste time

An art school specializes in metal sculptures and to save money and space they don't have a metal workshop with traditional power tools and cutting torches. To make the sculptures the students gather scrap metal and use a specialized steamer that heats the already thin metal enough to easily bend and can be used inside around other flammable materials as it is steam powered. The steamer creates the steam and then heats it through a funnel from 100 to 450 °C. Use steam tables to find what the heat input in Watts (W) of the funnel is if a continuous stream of steam at a rate of 50 kg/s undergoes the heating process at a constant pressure. Assumption: We are assuming that the P(bar) of saturation is at 0.1 for our steam tables

3.56 Refrigerant-12 in a piston/cylinder arrangement is initially at 50° C, x = 1. It is then expanded in a process so that P = Cv to a pressure of 100 kPa. Find the final temperature and specific volume.
