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?

Consider an ideal Hampson-Linde cycle in which no heat is lost to the environment. Use the data in attached Table to calculate the fraction of nitrogen liquefied on each pass through a Hampson-Linde cycle operating between 1 bar and 100 bars, with an input temperature of 300 K. Assume that the heat exchanger works perfectly, so the temperature of the low pressure gas coming out of it is the same as the temperature of the high-pressure gas going in. Repeat the calculation for an input temperature of 200 K.
Question 1)Water vapor enters with a continuous flow adiabatic turbine, 3MPa press, 400 oC temperature and 90 m3 / min volumetric flow rate. Some of the steam comes out of the turbine at a pressure of 0.5 MPa and a temperature of 200 oC. The remainder is abandoned in the 5 kPa pressure and 90% composition registration system. Calculate the mass flow rate at the outlet no. 2 by neglecting the kinetic and potential energies according to the total power generated in the turbine 5 MW. Question 2)Bir evin çatısına yerleştirilmiş güneş panelinin üzerine 2.5 kW’lık güneş enerjisi gelmektedir. Gelen bu enerjinin %25’i çevreye kaybedilmekte, kalan enerji ise güneş paneli içerisinden geçen suyun sıcaklığını 30 oC’den 60 oC’ye çıkarmak için kullanılmaktadır. Sürekli çalışma koşulları altında, su sıcaklığındaki istenen artışın sağlanabilmesi için güneş paneli içerisinden saatte kaç litre su geçmesi gerektiğini belirleyiniz. Suyun yoğunluğunu 1000 kg/m3 olarak alabilirsiniz. Ayrıca, güneş paneli…

Question 2)2.5 kW of solar energy comes upon renovation of a house. 25% of this incoming energy is lost to the environment, and the remaining energy is used to increase the temperature of the water passing through the solar panel from 30 oC to 60 oC. Determine how many liters of water pass through the solar panel in order to ensure the increase in water temperature under continuous operating conditions. Use the density of the water as 1000 kg / m3. Also, neglect the pressure loss, kinetic and potential energy…
