- On the T-v diagram, sketch the constant-specific-volume process through the state T = 120°C, v = 0.7163 m3 /kg from P1 = 100 kPa to P2 = 300 kPa. For this data set, place the temperature values at states 1 and 2 on its axis. Place the value of the specific volume on its axis.arrow_forwardAir is expanded in an internally reversible process from p1=10.29 bar and T1=1200K to a final pressure of p2= 1.00 bar. Determine all properties of the initial and final states (T,p,v,h and u), calculate the work of the process per unit mass, and sketch the process in the T-s and p-v diagrams assuming ideal gas behavior in the 4 following cases. Adiabatic reversible expansion in an ideal turbine (1 inlet and 1 outlet); Adiabatic reversible expansion in a (closed) frictionless piston–cylinder device; Isothermal reversible expansion in an ideal turbine (1 inlet and 1 outlet); Isothermal expansion in a (closed) frictionless piston–cylinder device. Kinetic and potential energy terms are negligible in all processesarrow_forwardAmmonia contained in a piston-cylinder assembly, initially saturated vapor at 0˚F, undergoes an isothermal process during which its volume (a) doubles, (b) reduces by half. For each case, fix the final states by giving the quality or pressure, in lbf/in2 , as appropriate. Locate the initial and final states on sketches of the p-v and T-v diagrams.arrow_forward
- 1 kg of H 2 O is contained in a rigid, insulated cylindricalvessel. The H 2 O is initially saturated vapor at 120°C. The vessel is fitted with a paddle wheel from which a mass is suspended. As the mass descends a certain distance, the H 2 O is stirred until itattains a final equilibrium state at a pressure of 3 bar. The only significant changes in state areexperienced by the H 2 O and the suspended mass. Determine, in kJ,(a) the change in exergy of the H 2 O.(b) the change in exergy of the suspended mass.(c) the change in exergy of an isolated system of the vessel and pulley–mass assembly.(d) the destruction of exergy within the isolated system. Let T 0 = 293 K(20°C), p0 = 1 bar.arrow_forwardcan water ever acts counter to entropy to perhaps stop a reaction from moving forward?arrow_forwardDetermine the temperature, in °C, of Butane at 30 bar and a specific volume of 0.026 m³/kg. Hint - you need to use compressibility charts since Butane is non-ideal under the specified conditions. Answer:arrow_forward
- 2.00-mol of a monatomic ideal gas goes from State A to State D via the path A→B→C→D: State A PA=10.5atm, VA=11.00L State B PB=10.5atm, VB=6.00L State C PC=24.0atm, VC=6.00L State D PD=24.0atm, VD=23.50L Assume that the external pressure is constant during each step and equals the final pressure of the gas for that step. Calculate q for this process. Calculate w for this process. Calculate ΔE for this process Calculate ΔH for this process.arrow_forwardAn ideal gas is changed from p1 = 1bar, v1= 10m3 to p2 =10 bar , v2 = 1m3 , calculate Q & W for the follwing process: a- Isothermal process. b- adiabatic compression followed by cooling process at constant pressure. c- Heating at constant volume followed by cooling at constant pressure? Take Cp= (5/2)R & Cv=(3/2) Rarrow_forward2) Using the tables for water, determine the specified property data at the indicated states. In each case, locate the state on a sketch of the p–v diagram. a)At p = 3 bar, v= 0.5 m3/kg, find T in °C and u in kJ/kg. b)At T = 320°C, v= 0.03 m3/kg, find p in MPa and u in kJ/kg. c)At p = 28 MPa, T = 520°C, find in m3/kg and h in kJ/kg.arrow_forward
- A gas having cv=0.7452kJ/kg.K undergoes a process in which delta h is equals to 400kJ/kg and delta u is equals to 320 kJ/kg. Determine a.) k; b.) cp (in kJ/kg-K) and c.) R (in kJ/kg-K) for this gas.arrow_forwardWho is right? A student thinks that in the open air at 25°C, water vaporizes slowly, and therefore finds in the presence of its steam. Or a student referring to the water state diagram and under an atmosphere water claims that water can only be entirely in liquid form. To which Error of reasoning is due to this "contradiction"?arrow_forwardOne kilogram of water ( ̄V1 = 1003 cm3/kg)in a piston/cylinder device at 25 and 1 bar is com-pressed in a mechanically reversible isothermal processto 1500 bar. Determine Q, W, ∆U, ∆H and ∆S giventhat β = 250 ×10−6K−1 and κ = 45 ×10−6 bar−1. Assume that ̄V is constant at its arithmetic average value.arrow_forward
