Air, modeled as an ideal gas, enters a well-insulated diffuse operating at steady state at 270K with a velocity of 180m/s. For negligible potential energy effects, determine the exit temperature in K. The exit velocity is 48.4 m/s.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Select any two (2) areas of applications of chain-drive. (clo4) a)-permanent lubrication necessary b)-hydraulic forklift truck operation c)-rigging and heavy moving materials d)-relatively high maintenance costs e)-costlier than belt drives

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.
