It is proposed to modify the heat engine in Q8 in such a way that it will now require exactly 200 kJ/s of heat to drive it. Which of the below “laws” would such a heat engine violate   a. The first law of thermodynamics b. The law of conservation of linear momentum c. The law of conservation of energy d. The law of conservation of mass e. The second law of thermodynamics

An electric home stove with 3 burners and microwave is used in preparing a meal as follows. Burner 1: 20 minutes Burner 2: 40 minutes Burner 3: 15 minutes . Microwave: 30 minutes. If each burner is rated at 1.2 kW and the oven at 1.8 kW, and electricity costs 1000 (IQ =Iraqi Dinar) per k Wh, calculate the cost of electricity used in preparing the meal?

Derive the 7 General Property equation of the following thermodynamic processes: 2. Isothermal Process

A Carnot engine operates between temperature levels of 600 K and 300 K. It drives a Carnot refrigerator, which provides cooling at 250 K and discards heat at 300 K. Determine a numerical value for the ratio of heat extracted by the refrigerator (“cooling load”) to the heat delivered to the engine (“heating load”).

A gasoline engine has a power output of 200 kW. Its thermal efficiency is 32%. (a) How much heat must be supplied to the engine per second? (b) How much heat is discarded by the engine per second? Note: please answer asap! I really need help

THERMODYNAMICS 1. Calculate the amount of energy required in BTU to heat the air in a house 30 by 50 by 40 ft from 10 to 70°F at constant pressure.  2. Brine enters a cooler at the rate of 50 m3/hr at 15°C and leaves at 1°C. Specific heat and specific gravity of brine are 1.07 kJ/kg–K and 1.1 respectively. Calculate the heat transferred in kW.  3. How many BTU/min is required to produce 10 metric tons of ice per day at -10°C from raw water at 22°C? The latent heat of fusion of ice is 335 kJ/kg.
