Write a program to solve the general case of Problem 6.111, in which the initial state and the expansion ratio are input variables.
Problem 6.111
The power stroke in an internal combustion engine can be approximated with a polytropic expansion. Consider air in a cylinder volume of 0.2 L at 7 MPa, 1800 K, shown in Fig. P6.111. It now expands in a reversible polytropic process with exponent n = 1.5 through a volume ratio of 10:1. Show this process on P-v and T-s diagrams, and calculate the work and heat transfer for the process.
Draw free body diagram of columns and beams for section AA. Assume EI as constant throughout, and consider the dimensions and loads given in excel file attached.
Mark's refrigerator has just died. He can get a basic fridge or a more efficient fridge with an Energy Star designation. Mark wants to consider a 10 year planning horizon using an interest rate of 5%.
During frequent braking under race conditions the disk brake rotors on the car described above reach a temperature of 500C. These disk brakes rely on forced convection to cool them. The dimensions of each disk rotor are: outer radius 130mm
A gas is compressed at a constant pressure of 0.800 atm from 9.00L tp 2.00L. in the process, 400J of energy leave the gas by heat. (a) What is the work done on the gas? (b) What is the change in it internal energy?
The given distances between points in this project area were computed from SPCS83 state plane coordinates. What horizontal length would have to be observed to lay off these lines on the ground? (Use 6,371,000 m for an average radius for the Earth...
Provided that the amplitude is sufficiently great, the human ear can respond to longitudinal waves over a range of frequencies from about 20 Hz to about 20000Hz. Compute the wavelength corresponding to these frequencies a.) for waves in air ( v= 344 ..
At that time, there is no more fuel in the rocket engine and the rocket continues upwards in free fall (g=0 ft/sec/sec). (a) How high will the rocket reach before it begins to fall back to the campus
a) Density plot, locating γd(max) and ω opt on the plot b) Zero-air voids curve for the soil on the same plotc) Curve representing S = 70%
A 1:2000 scale tidal model is operated to satisfy Froude's law. A velocity of 0.02 ft/s is observed in the model. What is the velocity at the corresponding point in the prototype
Trips can be classified by productions/attractions or origins/destinations. Which classification provides the direction of travel. Describe the product/outcome (e.g., production-attraction matrix) after each of the 4-step transportation planning pr..
