Please, complete solution with given. thank you. Thermodynamics subject
You have decided now that quarantine is about over to take a trip to Hawaii. You decide to rent a small house that has floor to ceiling windows. It is small so it is one floor. The length and width of the windows are 9m x 14m. There are 4 of them. It is a constant 950F (350C) outside and you really like it 650F(180C) inside. You have an air conditioner that operates at 75 percent Carnot efficiency. The windows are 6cm thick and the rest of the house is well insulated.
a) How much electrical energy do you use in a day?
b) What is the cooling capacity each day?

- Refrigerant-134a is in an insulated canister with temperature 25 C. There is a partition in the canister so the refrigerant is a saturated liquid and takes up 1/100 of the volume of the canister. The rest of the volume is evacuated. When the canister is activated by squeezing (no work done activating) the partition breaks and the refrigerant fills the total volume. Final pressure is 100 kPa. a.) What are two assumptions needed for the problem? What properties are needed to solve part b.) and c.) b.)

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 tablesarrow_forward
