After graduation, you decided to work overseas to experience living in a country with four seasons. Your neighbour, knowing that you are an engineer asked your help to install a heat pump system for his house. He wanted to always maintain the temperature in his house at 24°C during winter. In that area during winters, average outside temperature is -3°C. He also has an underground water well with average water temperature of 10°C during winter. You estimated that the heat losses from the house under the average outside temperature to be 75000 kJh. Investigate the most economical mean to power the heat pump (by calculating the minimum power required) if you can choose to extract heat from either: i. The outside air at average temperature of -3°C ii. The well water at 10°C State the reasoning for your calculations.

Prepare a report on the heating systems available in your area for residential buildings. Discuss the advantages and disadvantages of each system and compare their initial and operating costs.
You need an apartment for rent and as shown in the figure, you can see that the 3rd floors of each of the 2, 3 and 4 blocks of the buildings, whose front faces are adjacent, are for rent. You also learn that Block 2 is heated by a coal boiler operating at 75% efficiency, Block 3 is heated by a natural gas boiler operating at 92% efficiency and Block 4 is heated by a heat pump with a COP (coefficient Of Performance) of 4.5. We know that the heating process takes place uninterruptedly for 150 days, during these 150 days, the interior of the apartment remains constant at 22 °C. average outside temperature T∞ = 0 °C and average of wind speed u* = 5 m/s Find the total heating cost for all three blocks. The average heat transfer coefficient in apartment is h inside = 10 W/m2K thermal resistance of the wall Rwall = 1 m2K/W Assume that heat is lost only from the front and back of the blocks. In addition, the electricity unit price of 0.71 $/kWh, natural gas unit price of 0.14 $ / kWh, unit…

FTP لاطول مار 25 DBT, 50 % RH Outdoor design condition: 43 DBT and 27.5 WBT Bypass factor of the cooling coil = 0.1 Seta The return air from the space is mixed with the outside air before entering the cooling coil in the ratio of 4/ by weight. 도 Determine: SHYLH h₂-hy Ess=fre-pdo 4₂-4.
Q2) A plate having a thickness of 4.0 mm has an internal heat generation of 100MW/m and a thermal conductivity of 50 W/m'C. One side of the plate is insulated and the other side is maintained at 100 C. Calculate the maximum temperature in the plate.
The energy required to heat a 50m^2 living area in Canberra is of 18738 MJ per year.Assume the external air temperature in Canberra is 6℃, while the desired internal airtemperature is 19℃.The living area can be heated by electric element heater (assume it convert 100% ofelectricity into heat), by heat pump operating between the external and internal airtemperatures with coefficient of performance 3.0 and by a reversible heat pump operatingbetween the same temperatures. Consider for the electricity the cost of 22 cents per kWh.Question:(a) Determine the annual cost of heating the living area with the three systems above.(b) Determine for the two heat pumps the amount of energy per year received from theexternal air.

Come up with one problem related to energy balance for open system?
energy can be conserved when your home heating/cooling system works less during the heating and cooling seasons. in fact/ a one degree celsius difference in your thermostat setting can reduce energy consumption by up to 5%
If I have a simple piston-cylinder heat engine, where air is the working system and constant heat is applied, thereafter a mass is applied to the piston creating a higher pressure (reduction in volume), would this process be considered isothermal or polytropic? The walls of the cylinder are not insulted either.
Elina is a businesswoman who is looking for a new invention to invest. One of the entrepreneur claimed to have a device which has 50 kJ of heat transfer at 500 K. The device having heat transfer of 250 K released to the environment and does 20 kJ of work. If you were Elina, would you willing to be one of the investor for the device?
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
