Steam with initial parameters p1 = 0.1 MPa and t1 = 390 °C was expanded isentropically to a pressure of 0.03 MPa and then heated isobarically, providing 472 kJ/kg of heat. Determine the parameters of the steam (p, v, t, h, s, x) in the characteristic states of transformations. Draw the graphical illustration of the processes in the h - s, p – v, and T – s diagrams. Calculate the unitary volumetric work and the unitary net (technical) work of both transformations. If someone can hept me to find the value of p, c ,t,h,s,x for each state ?

Hello, Does anyone know typical values of cutoff ratio in diesel engines? And how have they evolved through time? Thank you!
