Estimate the greenhouse gas emissions from power production for the following threescenarios. Focus on the greenhouse gas emissions associated with theoperational energy, not the greenhouse gas emissions associated with the manufacture of theproduct or end of life processes.The hourly load demand for a home is given.1)  All power during an hour of up to 5 kW is drawn from a baseload coal powerplant. Any power in excess of that amount is drawn from a peaker plant running as anatural gas combined cycle power plant.2) Localized solar energy production is provided in the table on the next page.Energy demand by the house is first met by this solar generation. If the total hourlyenergy demand is below 5 kW, then any extra energy required beyond that provided bythe solar panels is drawn from a coal power plant. If the total hourly demand is above 5kW, then any extra hour demand beyond 5 kW is met by a natural gas combined cyclepower plant. No credit is given if the solar energy production…

Pls. Answer thank you! A logging firm in Isabella operates a Diesel Electric Plant to supply its electric energy requirements. During a 2 hour period, the plant consumed 250 gallons of fuel at 80°F and produced 2900 kW-hrs. Industrial fuel is used at 30°API and was purchased at P30/li at 60°F. Determine the overall thermal efficiency in percent of the plant.

2.0 What is the highest possible theoretical efficiency of a heat engine operating with a hot reservoir of furnace gases at 2000'C when the cooling water available is at 10°C? Ans. 87.54%

To have an efficiency of 40%, a heat engine that exhausts heat at 350K must absorb heat at no less thanA. 210 KB. 875 KC. 583 KD. 1038 K

A split air conditioner is used to heat an office in winter and cool it in summer.For this purpose, a split air conditioner with a cooling power of 1200 Btuh (3.5 kw) is used for the office. The power drawn by the split air conditioner is 1.2 kw accordingly. a) COP value b) If the outdoor temperature of the air conditioner is kept 22 C in summer, calculate the limit values for heating and cooling COP if the outdoor temperature in summer is 42C and the outside temperature in winter is -6C
