Air, at po = 160 lbf/in2 and To = 300°F, flows isentropically through a converging-diverging nozzle. At section 1, where A1 = 288 in2, the velocity is V1 = 2068 ft/s. Calculate the inlet Mach number (Ma1) and the throat area (A*). The inlet Mach number is-------- . The throat area is---------- ft2.es Determine the inlet pressure (p1) and the mass flow rate (m.). Round the final answer to three decimal places. The inlet pressure is ----------- lbf/ft2. The mass...

ANSWER [0.54 and 1.63]
(b) Air flows through a converging-diverging nozzle. At point "A" in the converging section, the cross-sectional area is 50 cm2 and the Mach number was measured to be 0.4. At point "B" in the diverging section, the cross-sectional area is 40 cm2. Find the possible Mach numbers at point "B" Assume that the flow is isentropic and the air specific ratio γ-1.4 and the gas constant R: 287 J/kg K.

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
