Question 2. A household with electric resistance heating plans to switch from resistive heating to a ground source heat pump. Annual heat consumption of the house is 30 000 kWh. Investment cost of the heat pump is 21 000 €. Heat pumps COP is 4.0. How much are the annual savings compared to resistive heating after the change of the heating system (in kWh)? Average price of electricity is assumed to be 12 c/kWh. Round off your answer to one decimal digit and enter it without the unit.
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

A piston and cylinder machine containing a fluid system has a stirring device in the cylinder. The piston is frictionless and is held down against the fluid due to the atmospheric pressure of 101.325KPa. The stirring device is turned 10000 revolutions with an average torque against the fluid of 1.275mN. Meanwhile the piston of 0.6m diameter moves out of 0.8m. Find the net work transfer for the system.
A windmill produces 5 kW and is connected to a battery to charge it. The batterydue to resistive heating loses heat at a constant rate of 2 kW. Find the stored energyin the battery after 2 hours?
This question deals with a cylinder, which is upright. Here are the facts for the problem. Can you please help me with a clear diagram and then the right equations for net work and heat? There is a massless and frictionless piston inside the cylinder with two stops which prevent movement down the cylinder. But, the cylinder can still move upward. Under the Below the piston is 5 kg of water, 50% of which (by mass) is initially vapor at 120°C. Heat is gradually added to the water until the water reaches a final state of 400°C. The atmospheric pressure is 500 kPa. The stops don't affect the area. (1) Draw a P-V diagram for the process, which includes the isotherms at states 1 and 2. (2) A what temperature does the piston first lift off? At what temperature has the liquid turned to vapor? (3) What is the net work and heat transfer between the system and the surrondings between states 1 and 2. Are these transfers going into or out of the system?
Some water is heated and superheated steam occurs. Can you use specific heat to find this heat transfer? Explain why?
