Two heat engines are operated in series so that part of the energy expelled from engine A is absorbed by engine B with |QhB| = 0.750 |QcA|. Engines A and B have efficiencies eA = eB = 0.250 and engine A performs work WA = 275 J. Find the overall efficiency of the two-engine combination, given by e = (WA + WB) /Q|hA|
What is the ideal efficiency of a reversible heat engine cyclically operating between a source temperature of 600 degrees Kelvin and a sink temperature of 150 degrees Kelvin?
A typical temperature for surface water in a tropical ocean is 27°C. Whereas at a depth of a kilometer or more it is only about 27°C whereas at a depth of a kilometer or more it is only about 5°C. It has been proposed to operate heat engines using surface water as the hot reservoir and deep water as the cold reservoir. What would the maximum efficiency of such an engine be? Why might such engine eventually be practical proposition even with so low an efficiency?
What is the Carnot efficiency (in percent) of a heat engine operating between the temperatures of 355°C (628 K) and 200°C (473 K)?
A heat engine rejects heat at a rate Q˙C = 30 kW into a reservoir at TC = 400 K . If it produces a net work of W˙ext = 35 kW , what is the minimum required temperature for the high temperature reservoir? Express your answer with the appropriate units to three significant figures.
One very special method for performing work is to do so reversibly. A change of state occurs reversibly if the external pressure equals the gas pressure throughout the change of state. If the change of state occurs isothermally (at constant temperature), then the expression for reversible work on an ideal gas is: w= -nRTln(V2/V1). Suppose 4.00 mol of an ideal gas undergoes a reversible isothermal expansion at 344 K from 12 L to 51 L. What is w (in J) for this change of state? Round your answer to the ones place.
What is the maximum efficiency of a heat engine whose operating temperatures are 660C and 340 C?
