The answer to this question is given as 140.7 deg C, but I have no idea how to get there

A rigid tank with a volum of 2.5m^3 contains 5kg of saturated liquid-vapor mixture of water at 75deg C. Now the water is slowly heated. Determine the temperature at which the liquid in the tank is completely vaporized. Also show the process on a T-v diagram with respect to saturation lines.

What would be the predicted l for the prototype

The same fluid is to be used in both the model and the prototype, but γ (model) = 9 × γ(prototype). (a) If V= 50 mph, at what velocity should the model tests be run?

Explain what the circuit does

1. The input to the circuit of Figure P12.76 is a square wave having a period of 2 s, maximum value of 5 V, and minimum value of 0 V. Assume all flip-flops are initially in

Determining the control the strain rate

In superplastic forming, it is often necessary to control the strain rate. Consider the forming of a hemispherical dome by clamping a sheet over a circular hole and bulging
