A gas flows through a horizontal 30-cm inside diameter pipe at the rate of 1080 kg/min. The pipe is at an elevation of 45 m above a reference plane. The pressure of the gas is 700 kPag when the barometric pressure is 750 mmHg. The density of the gas is 0.0016 g/cm3. (a) What is the mass velocity in kg/s-m2? Ans. 254.65 kg/s-m2 (b) Determine the linear velocity in m/s. Ans. 159.2 m/s (c) Evaluate the different forms of energy of the gas that can possibly be calculated from given data in kJ/kg.

Question
A gas flows through a horizontal 30-cm inside diameter pipe at the rate of 1080 kg/min. The pipe is at an elevation of 45 m above a reference plane. The pressure of the gas is 700 kPag when the barometric pressure is 750 mmHg. The density of the gas is 0.0016 g/cm3.
(a) What is the mass velocity in kg/s-m2? Ans. 254.65 kg/s-m2
(b) Determine the linear velocity in m/s. Ans. 159.2 m/s
(c) Evaluate the different forms of energy of the gas that can possibly be calculated from given data in kJ/kg.
PE = 0.441 kJ/kg
KE = 12.67 kJ/kg
FE (flow) = 500 kJ/kg
