A heat engine with a thermal efficiency of 45% rejects 1000 kJ/kg of heat to a low temperature sink. How much heat does it receive(kJ/kg)? How much work does it produce (kJ/kg)? If the cycle operates between temperatures of 400°C and 50°C, what is the maximum amount of work that this cycle can produce (kJ/kg)? A Carnot heat pump operates between 273 K and 313 K, determine its Coefficient of Performance.

Question

I need help with the steps of this thermodynamics review sheet! Thank you 

A heat engine with a thermal efficiency of 45% rejects 1000 kJ/kg of heat to a low temperature sink.

  1. How much heat does it receive(kJ/kg)?

  2. How much work does it produce (kJ/kg)?

  3. If the cycle operates between temperatures of 400°C and 50°C, what is the maximum amount of work that this cycle can produce (kJ/kg)?

  4. A Carnot heat pump operates between 273 K and 313 K, determine its Coefficient of Performance.
