Two kilograms of saturated water mixture at 200◦C, x = 0.5 is heated in a constant-pressure process to 300◦C in a piston-cylinder arrangement.

1. Find the initial and final volumes and the total heat transfer required.

2. Track the process in steps of jumps of 5% in the quality, after that use steps of 10◦C until final state

is reached. Plot the relationship between the heat transfer vs the volume and the work done vs

the volume.

In a wind tunnel the speed changes as the cross sectional area of the tunnel changes. if the speed in a 6' x 6' square test section is 100 mph, what was the speed upstream of the test section where the tunnel measured 20' x 20'? use conservation of mass and assume incompressible flow. conservation of mass requires that as the flow moves through a path or a duct the product of the density, velocity and cross sectional area must remain constant; i.e., that ova-constant. a model is being tested in a wind tunnel at a speed of 100 mph if the flow in the test section is at sea level standard conditions, what is the pressure at the model's stagnation point? (a) the tunnel speed is being measured by a pitot-static tube connected to a u- tube manometer. what is the reading on that manometer in inches of water? (b) at one point on the model a pressure of 2058 psf is measured. what is the local airspeed at that point?
