Consider an aircraft in a flow with freestream properties 1 atm and 519R. A pitot tube on the aircraft measures a pressure of 2.5 atm. Problem 1 Answer 1. Is the flow supersonic or subsonic? 2. Determine the Mach No. of the aircraft 1. Is the flow subsonic or supersonic?

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
