Air is allowed to flow from a reservoir with temperature of 21°C and with pressure of 5[MPa] through a tube. It was measured that air mass flow rate is 1[kg/sec]. At some point on the tube static pressure was measured to be 3[MPa]. Assume that process is isentropic and neglect the velocity at the reservoir, calculate the Mach number, velocity, and the cross section area at that point where the static pressure was measured. Assume that the ratio of specific heat is k = C/C, = 1.4. Air is allowed to flow from a reservoir with temperature of 21°C and with pressure of 5[MPa] through a tube.
