Transcribed Image Text:Unless otherwise stated, take R = 287 J/kg K for air (model as a perfect gas at standard
atmospheric pressure and temperature), p = 1000 kg/m³ for water, p = 13530 kg/m³ for
Mercury and g = 9.81 m/s².
%3D
Express answers as gauge pressures unless otherwise stated.
1. Air flows along a pipe with velocity 30 m/s, and a water manometer attached to a
pressure tap in the pipe wall shows a differential head of 150 mm above atmospheric
pressure. Calculate:
a. The static pressure on the pipe wall
b. The dynamic pressure
C.
The stagnation pressure
