Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing.

A reversible refrigerator operates using a Carnot refrigeration cycle. It operates usingr-134a between 140 and 400 kPa. The refrigerant exits the compressor (and enters the condenser) assaturated vapor. It also leaves the condenser as saturated liquid.a. Sketch the P-v and T-s diagram of this cycle. Define the coordinate properties of each state oneach graph.b. Evaluate the specific heat and specific work properties of each (in kJ/kg). Indicate the sense.c. Evaluate the coefficient of performance using the specific heats and works from the previousitem. Did it match with the COPR obtained if you used the operating temperatures? Solve for states first. Then, show the solution to each of the above required in order.
A two stage refrigeration cycle is shown in fig. B. The working fluid is refrigerant 134a. The interchanger is a heat exchanger where the heat absorbed by the refrigerant in the higher-temperature cycle 2 serves to condense the refrigerant in the lower-temperature cycle 1. The refrigerant in cycle 1/2 leaves the interchanger as saturated liquid/vapor. The corresponding temperatures of saturation are 5.12 ℉ / 0 ℉. The saturation temperature in the evaporator is -40 ℉. The pressure in the condenser is 60 psia. The compressor in cycle 1 operates isentropically. The compressor in cycle 2 has an isentropic efficiency of 80%. (a) Sketch the cycle in a T-s diagram and determine the enthalpy at each point of the cycle. (b) Calculate the ratio of the mass flow rates of the refrigerant in the two cycles. (c) Calculate the coefficient of performance of this refrigeration cycle.
