Q9. Argon is compressed in a polytropic process with n = 1.2 from 127 kPa and 11 °C to 615 kPa in a piston-cylinder device. R₁ = 8.314 kJ/(kmol-K), MAr = 39.948 kg/kmol, c, = 0.3122 kJ/(kg.K). Argon can be assumed as ideal gas and c, is assumed constant. Determine the heat transferred during this compression process, in kJ/kg. Negative sign must be included if the heat is transferred from the system. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point.
Q1. The pressure in a natural gas pipeline is measured by the manometer shown in the image with one of the arms open to the atmosphere where the local atmospheric pressure is 99 kPa. The dimensions are a = 30 cm, b= 13 cm, c = 5 cm, and d = 60 cm. Determine the absolute pressure (in kPa) in the pipeline. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. Take g = 9.81 m/s2, and Pwater = 1000 kg/m³. Natural Gas a b Air C of d
