A Carnot engine with an efficiency of 30% operates with a high-temperature reservoir at 188oC and exhausts 2000 J of heat each cycle. What are (a) the heat input per cycle and (b) the Celcius temperature of the low-temperature reservoir

a) The heat input per cycle is 2857.143 joules.

b) The temperature of the low-temperature reservoir is 49.655 °C.

Explanation:

a) The efficiency of the Carnot engine is defined by the following formula:

(1)

Where:

- Low temperature reservoir, in Kelvin.

- High temperature reservoir, in Kelvin.

 - Heat output, in joules.

- Heat input, in joules.

- Engine efficiency, no unit.

If we know that and , the heat input of the Carnot engine is:

The heat input per cycle is 2857.143 joules.

b) If we know that and , then the temperature of the low-temperature reservoir:

The temperature of the low-temperature reservoir is 49.655 °C.

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

where's the following? you gotta add it to know what the choices are
