A Diesel cycle operates with a compression ratio of 14 and with a cut-off occurring at 5% of the stroke. Find the cut-off ratio, if the initial volume is 1.5 ft3. O 1.64

As shown in the figure, a chamber with a moveable piston and containing a monatomic ideal gas in an initial state A undergoes an isovolumetric, then an isothermal, and finally an isobaric process to complete the cycle. P (atm) LV (L) When the gas is in the initial state, the volume is 3.00 L, the pressure is 5.00 atm, and the temperature is 200 K. The gas is first warmed at constant volume to a pressure of 4 times the initial value (state B). The gas is then allowed to expand isothermally to some new volume (state C). Finally it is compressed isobarically to its initial state. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.)

Calculate the net work output of a heat engine following path ABCDA in the figure below, where  V1 = 2.6 ✕ 10−3 m3  and  V2 = 10.4 ✕ 10−3 m3.

Suppose a heat engine design makes a square on a PV diagram, using a monatomic gas. The high pressure is 3P and low pressure is P. The high volume is 3V and low volume is V. What is the efficiency of the heat engine?

An engineer decided to design a hybrid engine half-way between the Carnot and Otto Cycles based on using 35 moles of a diatomic gas. It features (a) an adiabatic expansion for power, (b) an isothermal compression to reset, and (c) an isovolumetric temperature injection. Some of the key state values are given on the P-V chart for the transition points between the processes. What is the 1) net work performed by the engine, 2) the amount of heat injected the isovolumetric temperature increase (QH), and 3) based on these values, what is the efficiency of the engine?Solve for other state variables as necessary   How much more efficient would a Carnot engine be acting between these same temperatures?
