A. Show that dp Determine the final density and enthalpy of the water: P (a) if it is heated to 50°C at a constant pressure of 1.0 atm. (b) if it is compressed to 100 atm pressure at a constant temperature of 20°C. Assume the following equations applicable for water at given operating conditions kr = (0.0037 T² - 0.3138 T + 50.768) x10- where T in "C where T in °C B = (-0.1007 T² + 15.373 T-63.261) x10-6 kydP - BdT. Consider water initially at 20°C and 1.0 atm have 998 kg/m (bar ¹) (K-¹) (Note: do the density calculations based on the derived equation and without using any steam tab

The figure below is the basic plot of pressure vs. volume for the Dual Standard Cycle. Constant pressure heat addition 3 4 = constant Нeat IN Adiabatic expansion Heat OUT (Constant volume heat rejection) Constant volume heat addition Adiabatic compression Volume (V) Using the Dual Air Standard Cycle and the following data: Assume constant properties of air. R= 287 J/kgK; Cp = 1005 J/kgK; Cv = 718 J/kgK;y = 1.4 Cycle compression ratio = 11 (v1/v2) Air conditions prior to compression: Pressure = 1.6 bar; Temperature = 298K Heat added at constant volume = 290000 J/kg Heat added at constant pressure = 579000 J/kg a) Calculate the pressure at the end of the compression process. P2 = bar Pressure (P) LO

During methane liquefaction, about 1000 kg of methane are stored at a pressure of 10 MPa and 180 K. The plant manager is worried about the possibility of explosion of the storage tank. Determine the energy released (in kg TNT equivalent) by a sudden rupture of this storage tank and the temperature and physical state of the methane immediately after the rupture.

Stefan-Boltzman law which describes the radiation heat transfer states that, it is proportional to (where, t = temperature in °C T = absolute temperature in °K) A. +4 T4 B. C. D. O 1 t4 1 T4

The rate of heat transfer from a body to the surroundings is governed by the following equation: D= hA(Tsur - Tbody) Where dis the heat transfer rate (J/s) h is the heat transfer coefficient A is the heat transfer area (m²) Tsur is the temperature of the surroundings (K) Tpody, is the temperature of the body (K) Find the units for the heat transfer coefficient, h.
