Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.

Consider a flow through an exhaust valve. The cylinder pressure is 400 kPa. Determine the minimum exhaust pressure which does not choke the flow. (Assume k = 1.35). O 328.2 kPa O 266.8 kPa O 400 kPa 100 kPa O 186.35 kPa O 146.9 kPa O 214. 8 kPa O The flow will never be choked regardless of the value of the exhaust pressure.
Air is allowed to flow from a tank with temperature of 69.8 °F and with pressure of 49.3461 atm through a pipe. It was measured that flow rate is 2.2046 lbm/sec. At some point on the tube static pressure pressure was measured to be 22501.845 mmHg. Assume that process is isentropic and neglects the velocity at the reservoir, calculate the pipe diameter (answer in whole number, unit is mm). Assumed that the ratio of specific heats is 1.4.

a2/ The flow velocity of water in a pipe is measured by a pitot static tube. The tube is placed at the centre of a 30 cm diameter pipe. The difference between the stagnation and static pressures measured as head of mercury and converted to head of water is 10 cm. If the coefficient of velocity Cv = 0.98. determine the velocity of water in the pipe. If the mean velocity is 0.7 times the centre line velocity, compute the discharge of water through the pipe.
