Aradar system is used to track a new experimental space launch vehicle. early in the vehicle’s flight trajectory, the azimuth angle β is increasing with the constant rate dβ/dt = 26°/s. the elevation angle γ is increasing at the rate dγ/dt = 40°/s, and this rate is increasing at 5°/s2. know that the distance between o and p is 2 m and that at this instant β = 0° and γ = 30°.

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.
