Chapter 21: Q. 2 (page 593)

Rank in order, from largest to smallest, the amount of work W51toW54done by the gas in each of the cycles shown in FIGURE Q21.2. Explain.

Short Answer

Expert verified

Rank in order isW3>W2=W1>W4

Step by step solution

01

Step :1 Introduction 

The work done in thermodynamics is represented by the area under the PV diagram. In order for work to be done in a closed system, there must be some volume displacement. In other words, an isochoric process (volume = constant) produces no work.

02

Step :2 Explanation

When a closed loop is established in a clockwise manner, the quantity of work performed by the system equals the area enclosed by the loop.

A Carnot heat engine operates between reservoirs at 182掳Cand 0掳C. If the engine extracts 25Jof energy from the hot reservoir per cycle, how many cycles will it take to lift a 10Kg mass a height of 10m?

Engineers testing the efficiency of an electric generator gradually vary the temperature of the hot steam used to power it while leaving the temperature of the cooling water at a constant 20掳C. They find that the generator鈥檚 efficiency increases at a rate 3.5脳10-4K-1at steam temperatures near 300掳C. What is the ratio of the generator鈥檚 efficiency to the efficiency of a Carnot engine?

The coefficient of performance of a refrigerator is6.0 . The refrigerator's compressor uses 115Wof electric power and is 95%efficient at converting electric power into work. What are (a) the rate at which heat energy is removed from inside the refrigerator and (b) the rate at which heat energy is exhausted into the room?

FIGURE CP21.70shows two insulated compartments separated by a thin wall. The left side contains 0.060molof helium at an initial temperature of 600Kand the right side contains 0.030molof helium at an initial temperature of 300K. The compartment on the right is attached to a vertical cylinder, above which the air pressure is 1.0atm. A 10-cm-diameter,2.0kg piston can slide without friction up and down the cylinder. Neither the cylinder diameter nor the volumes of the compartments are known.

a. What is the final temperature?

b. How much heat is transferred from the left side to the right side?

c. How high is the piston lifted due to this heat transfer?

d. What fraction of the heat is converted into work?

The power output of a car engine running at 2400rpmis 500kW. How much (a) work is done and (b) heat is exhausted per cycle if the engine's thermal efficiency is 20%? Give your answers inKJ.
