Acarnot engine has a power output of 148 kw. the engine operates between two reservoirs at 17◦c and 727◦c. how much thermal energy is absorbed each hour? answer in units of j.

The thermal Energy absorbed each hour = 750420 kJ

Explanation:

Efficiency of a Carnot engine = W/Q = (Th-Tc)/Th Equation 1.

W/Q = (Th-Tc)/Th

making Q the subject of the equation above,

Q = W(Th)/(Th-Tc) Equation 2

Where Q = input power, W = output power, Th = temperature of the hot reservoir, Tc = Temperature of the cold reservoir.

Given: W= 148 kW, Th = 727 °C = 727 + 273 = 1000 K, Tc = 17  °C =17 + 273 = 290 K.

Substituting these values into equation 2,

Q = 148(1000)/(1000-290)

Q = 148000/710

Q = 208.45 kw

The thermal Energy absorbed each hour = 208.45 kW × 3600 s

The thermal Energy absorbed each hour = 750420 kJ

plz mark.me the brainliest i rlly need this kind of yours in exchange

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
