Air flows through pipe. A Venturi meter is used to measure the mass flow. The temperature and static pressure of the air are 20.8 °C and 87.5 kPa respectively. The diameter of the pipe is 13 cm and the diameter of the throat is 11 cm. Assume the discharge coefficient of the venture meter as 0.97. A pressure difference of 395 Pa is measured over the Venturi. Determine the mass flow in the pipe.
