Classify internal combustion engines taking various factors into consideration. What is a thermodynamic temperature scale or absolute temperature scale? Explain the establishment of such a scale.

This question requires the use of the extracts from the tables of thermodynamic properties supplied. Dry saturated steam at a temperature of 25°C is cooled isentropically such that its temperature falls to 15°C. What is the dryness fraction after the cooling process? а. 0.93 О ь. 0.85 O c. 0.81 d. 0.97 е. 0.77

Use the following Data for Nitrogen gas: R= 0.2968 kJ/kg.K, C,=1.0418 kJ/kg.K, C,=0.745 kJ/kg.K, Required: Draw consistent, clear and standard schematic for the problem representing the inlet and outlet conditions and label your schematic with the given operating conditions. Analyze the problem systematically using step-by-step CV energy and mass analyses, state your assumptions (wherever applicable), and determine the following (circle your final answers): (a) The specific volume and density at the inlet and exit of the compressor; (b) The difference in the specific enthalpy between the exit and inlet of the compressor assuming a constant specific heat Cp; (c) The specific heat loss from the compressor;

Can you provide the step-by-step solution how to get the answers? Steam flows adiabatically through a nozzle from 1517 KPaa, 290 °C, to 965 KPaa. Sketch the pV and Ts diagram and for m=454 gm/sec, Determine delta s, delta u, delta v, delta h, work nonflow and work steady flow. the first three (delta s, delta u, delta v, delta h) were already answered. Can you continue the bold part
