1. Real heat engines, like the gasoline engine in a car, always have some friction between their moving parts, although lubricants keep the friction to a minimum. Would a heat engine with completely frictionless parts be 100% efficient? Why or why not? Does the answer depend on whether or not the engine runs on the Carnot cycle? Again, why or why not? 2.Some critics of biological evolution claim that it violates the second law of thermo- dynamics, since evolution involves...

A gas turbine engine is considered in a race car design. The engine operates on two stages of compression with intercooling and two stages of expansion. The pressure ratio across each stage of the compressor and the turbine is 7. The air enters each stage of the compressor at 300K and each stage of the turbine at 1300K. Using air standard assumptions determine: Thermal efficiency and back work ratio if no regenerator is used; Thermal efficiency and back work ratio...

An engineer is investigating engine life for a new oil compound. He has built 12 engines and tested them to end of life in a test. The sample mean was 63,000km. He has enough data to show that the populations standard deviation is equal to 3150km. He is stesting H0: mu = 62000km against H1: mu does not = 62000km, and using P(Type 1 error) = .05. If the true population mean tire life is 61000km what is the P(type...

1.An airoplane with four engines is able to fly if at least one engine is functioning on each wing. Let Ai be the event that the ith engine is working, i = 1, 2, 3, 4, where engines 1 and 2 are on the left wing and engines 3 and 4 are on the right wing. Let A be the event that the airoplane is able to fly. Express A in terms of A1, . . . , A4, using...

Part 1 You are to use your car to estimate its engine efficiency. When the car has been filled totally with fuel set the trip counter to zero, drive until it is filled again and note the mileage covered. In table 1, below, it states the energy for Gasoline (Petrol). Diesel and LPG. Calculate the energy of the fuel used. For this exercise, we will ignore times stuck in traffic, etc.. and to estimate the overall efficiency of the fuel...
