Chemical Engineering Basics

Q1: The efficiency of a Carnot heat engine operating between absolute temperatures T1 and T2 (when, T1 > T2) is given by (T1 - T2)/T1. The co-efficient of performance (CO.P.) of a Carnot heat pump operating between T1 and T2 is given by

A T1/(T1-T2)

B T2/(T1-T2)

C T1/T2

D T2/T1

ANS:A - T1/(T1-T2)

COP= output/input.
COP = Th/ Th-Tc .

Here Th is T1 and Tc is T2.
So, COP= T1/T1-T2.
