Answer is 0.93 kg/s. Show work.
7. Air flows through a 15cm pipe line which is fitted with a venturi meter with a 7.5cm throat. The gage pressure at the entrance to the meter is 1.36105Pa (relative) and the temperature is 20C. The differential manometer shows a reading of 15cm of meicury. Barometric pressure is 105Pa (absolute) and C can be taken as 0.93. Find the mass flow rate of air in kg/s
