## Refrigerant 134a leaves the evaporator as saturated vapor at

Refrigerant 134a leaves the evaporator as saturated vapor at 1.4bar and is heated at constant pressure to 20 degrees C before entering the compressor. After isentropic compression to 12bar, the refrigerant passes through the condensor exiting at at 44 degrees C, 12 bar. The liquid then passes through the heat exchanger, entering the expansion valve […]

## Fourier analysis using Excel

The supply current was sampled 1024 times over a very short time interval. The data so obtained is given in column B of the accompanying Excel worksheet (see attached). This worksheet has been set up to give a graph showing the spectral components of the data. Question 3 i) Obtain the Fourier Transform for the […]

## Pressure Cooker and Mass Flow Rate

Steam is leaving a pressure cooker whose operating pressure is 30 psi. It is observed that the amount of liquid in the cooker has decreased by 0.4 gal in 45 minutes after the steady operating conditions are established, and the cross-sectional area of the exit opening is 0.15 in^2. Determine (a) the mass flow rate […]

## Dog Legged Staircases

Dog legged staircase is one of the simplest form of staircases in which a flight of stairs ascends to a half-landing before turning 180 degrees and continuing upwards. It is also called this because of its appearance in sectional elevation. From a design point of view, the advantage of this staircase lies in its compact […]

## Bit Strings

A bit string is a string of bits (0â??s and 1â??s). The length of a bit string is the number of bits in the string. An example, of a bit string of length four is 0010. An example, of a bit string of length five is 11010. Use the Rule of Products to determine the […]
