An ideal Brayton cycle uses air as a working fluid. The air enters the compressor at 101 kpa and 37 C. The pressure ratio of the compressor is 12:1, and the temperature of the air as it leaves the turbine is 497 C. The temperature and the pressure of the surroundings are 37 C and 100 kpa, respectively. Use the air-standard assumptions and determine the following quantities: (a) The work per unit mass required to operate the compressor; (b) The work per unit mass produced by the turbine; (c) The heat transfer per unit mass during the combustion process and during the exhaust process; (d) The irreversibility of the cycle on a unit-mass basis, assuming the temperature of the low- and high-temperature reservoirs ar 37 C and 1300 C, respectively; (e) The thermal efficiency of the cycle.
what is the discussion of motion in one dimension for experiment 7
The process of apparent change in frequency (or wavelength) of the light because of relative motion among the source of light and the observer is known as Doppler's effect.
Theory of Light: Newton proposed 'Corpuscular Theory of Light'. 2. According to corpuscular theory, light consists of a stream of tiny, light and perfectly elastic particle
Is this wavelength in vacuum? Answer; as per mass of CPH is constant, and Vc is for an alone CPH, so wavelength should be in vacuum, that there is not any gravity effect. But i
why deflection magnetometer can not be worked at poles?
Resistors in dc circuits: Components are said to be in series when they are connected end-to-end providing only one path for the current. Thus the same current passes through
AC Output Resistance in Common Base Configuration Ratio of change in collector-base voltage ( ? V CB ) to resulting change in collector current ( ? I C ) at
what is thermal conductivity ?
Resistance measurements: An example of how to make AC voltage measurements is shown in the diagram below. Once again, the red and black test leads are connected to the '+' and
A box is initially at rest on a horizontal, frictionless table. If a force of 10 Newtons acts on the box for 3 seconds, what is the momentum of the box at the end of the 3 second i
