Question 1 (15 points) The reading on a mercury manometer at 25 C is 60 cm. The local gravity is 9.8 m/s. The local atmospheric pressure is 1 bar. The density of oil in the manometer at 25 C is 1.3 g/cm'. Determine: (a) The gauge pressure. (kPa) (b) The absolute pressure being measured (kPa). J pas Question 2 (35 points) A cylinder and piston device contains a gas at 25C. The mass of the piston is 100 kg. The local acceleration of gravity is 9.8 m/s2, the atmospheric pressure is 102 kPa. The cross sectional area of the piston is 0.04 m and the initial volume of the gas is 3 m. The molar mass of the gas is 28 g/mole. a) What is the force (kN) exerted on the gas by the atmosphere? (10 points) b) What is the absolute pressure of the gas (kPa)? (10 points) c) If the gas in the cylinder is heated up until the volume of the gas is 6 m', determine: () The work done (kJ). (5 points) (ii) The final temperature of the gas (10 points) Step by Step Solution
