Methane is to be liquefied in a simple Linde process. The feed and recycle are mixed, compressed to60 bar, and precooled to 300 K. The vapor then passes through a heat exchanger for additional coolingbefore being throttled to 1 bar. The un-liquefied fraction leaves the separator at the saturationtemperature, and passes through the heat exchanger, then exits at 295 K.CompressorPrecooler3.System IHeat ExchangerSystem II |4ThrottleValveFlash DrumlLiquidProduct(a) What fraction of the gas is liquefied in the process(b) what is the temperature of the high-pressure gas entering the throttle valve?

Answer are given all i need is the correct solution thank u
Problem 1 Starting with Gibbs equations, derive the temperature-volume ratio relationship and the temperature- pressure ratio relationship for an isentropic process of an ideal gas, using approximate analysis, i.e. constant specific heats. Show all steps.
Nm 2. An ideal gas has a gas constant of 319.8 - and a gas ratio of 1.26. Calculate kg K the heat rejected per kg of gas: A. when the gas is contained in a rigid vessel at 3 bar and 315°C and then cooled until the pressure falls to 1.5 bar. B. when the gas enters a pipeline at 280°C and flows steadily at constant pressure to the end of the pipe where the temperature is 20°C.
When the temperature of outside air at 35°C and 100 kPa is decreased to 27°C, condensation of the moisture in the air takes place. Find the partial pressure of the dry air, the relative humidity and the humidity ratio.
Question: 2 Calculate the specific volume, specific enthalpy, and specific internal energy at 80 bar, dryness fraction X=0.45.
Can anyone answer letter b? Thank you in advance! The manufacturing of pie filling involves blending of concentrated product with liquid sugar and heating by steam injection. The product being manufactured will contain 25% product solids and 15% sugar solids and will be heated to 115°C. The process has input streams of concentrated product with 40% product solids at 40 C and 10kg/s and liquid sugar with 60% sugar solids at 50 C. Heating is accomplished using steam at 198.53kPa. The concentrated product entering the process and the final product have specific heats of 3.6kJ/(kg C), whereas the liquid sugar has a specific heat of 3.8kJ/(kg C). Determine (a) the rate of product manufacturing; (b) the flow rate of liquid sugar into the process; (c) the steam requirements for the process; and (d) the quality of steam required for the process.

! Required information Problem 13.067 Piston NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A piston-cylinder device contains a mixture of 0.4 kg of H₂ and 1.2 kg of N2 at 100 kPa and 300 K. Heat is now transferred to the mixture at constant pressure until the volume is doubled. Assume constant specific heats at the average temperature. Problem 13.067.a Piston Determine the heat transfer. Use the table containing the ideal-gas specific heats of various common gases. The heat transfer is kJ.

A tank is being considered to mix a chocolate solution that has a 8.0 kW motor. This baffled tank is 1.25 m in diameter and 1.25 m high with a HE-3 impeller that is 0.36 m from the bottom of the tank. In order to sufficiently mix the chocolate solution, an agitation speed of 810 rpm will be needed. The motor efficiency is 70%. Is the Problem 1 motor adequate to mix the chocolate solution?
A steam/water mixture is contained in a vertical cylinder by a 100 mm diameter freely movable frictionless thin piston. The cylinder is fitted with a set of stops 40 mm above the cylinder base. Initially at State 1, the piston remains in equilibrium 10 mm above the cylinder base while the steam/water mixture is at a pressure of 1.5 bar with a dryness fraction of 0.25. (a) Find the mass of the steam/water mixture. The steam/water mixture is then slowly heated until the piston just reaches the stops at State 2. (b) Using appropriate calculations and reasoning, show that the cylinder contains superheated steam at State 2. The contents of the cylinder are further heated to increase the pressure to 3.0 bar at State 3. (c) Draw the entire heating process on a T-v diagram, indicating all states involved. (d) At State 3, determine the steam temperature and the force exerted by the stops on the piston. (e) Calculate the total work done by the contents in the cylinder from State 1 to State 3.
