please quickly.Thank you.Just part A Part a) and Part b) are separate questions to be solved independently.Part a) A vapor-compression refrigerator using R-134a is located in a 20°C room. Consider the cycle to be ideal, except that the compressor is neither adiabatic nor reversible. The mass flow rate ofR-134a in the cycle is 0.1 kg/s. Saturated vapor at -24°C enters the compressor, and R-134a exits the compressor at 40°C. Condenser pressure is 800 kPa, and the COP is measured and found as 2.i) Determine the power required by the compressor:kW.ii) Determine the heat transfer for the compressor:kW.kW/K.iii) Determine the rate of entropy generation in the compressor process:Part b) Air enters an adiabatic turbine at 11.3 MPa, 300 K, and exits at 3.75 MPa, 240 K. Use the enthalpy and entropy departure charts and table A-22For Air: R = 0.287 kl/kgK; Tcritical = 133 K; Peritical = 3.77 MPa

As a technologist, you are given the following design task: In a manufacturing environment, the final product needs to be packaged and sealed. After the product is placed inside the plastic bag, a hot pressing die is to be used to seal the plastic bag by application of heat and pressure. The operation should be as follow: By pressing a pushbutton switch, the heating rail is advanced and the packaging material is heated along the adhesive strip. After the adhesion pressure has been reached, the heating rail must return to its start position The design specification includes the following: Pressure dependent reversal with monitoring of the end position by means of magnetic proximity switches. Include safety measures, a green light to show when the system is ready, a red light when system is in operation, a warning sound when the heating rail is moving. 1. Draw your pneumatic circuit design for this application. 2. Draw the electric circuit diagram for your design.
