There is no cycle involved. You simply heat the air and gases to cause them to expand and make the propeller above to rotate.

I assume that the heat flow is in the vertical direction and the bottom is hotter than the top, so we do not need to include natural convection. Is this correct?

At the maximum hight of the siphon, when cavitation occurs, the absolute pressure is not zero, It is equal to the vapor pressure of the liquid.

In analyzing the mechanics of deformable membranes (such as, for example, the deformations and stresses within an automobile tire structure modeled as non-isotropic membrane), it is very convenient to use an embedded material coordinate system in which the material coordinates stretch and...

In scenario 2, the radius of the cylinder is found by ##2\pi R=1.2##or $$R=\frac{1.2}{2\pi}=\frac{0.6}{\pi}$$The pressure is given by $$P=\frac{T}{RW}=\frac{22.5\pi }{(0.6)(0.25)}$$

In the first scenario, there is definitely going to be significant widthwise contraction (and this would reduce the required tensile force) if, as indicated, the original width is much smaller than the original length. To avoid widthwise contraction in the first scenario, you would have to make...

In statistical thermodynamics, the following approximation is frequently used: $$\ln{(n!)}=\ln(1)+\ln(2)...\ln(n-1)+\ln(n)\approx \int_0^n{\ln{n'}dn'}=n\ln(n)-n$$so $$n!\approx n^ne^{-n}$$

Is the allowed to contract in width when scenario 1 is applied? Is it allowed to contract in with what scenario 2 is applied?

This is not a correct interpretation. The difference between H2O l enthalpy and H20 g enthalpy is primarily the result of the difference in internal energies of the liquid and vapor, with only a veery small contribution to the difference in PV.

I totally oppose introducing this description in an attempt to assign a physical interpretation to enthalpy. I have seen it accomplish nothing but causing confusion among generation after generation of neophytes to the subject of thermodynamics. Enthalpy is just a convenient shorthand...

Let's see you analysis so far, starting with your schematic of the system.

You need to be able to calculate the outlet temperature of the condenser. For this, you need to know the heat transfer coefficient between the air and the heat transfer surface. This is a function of the flow velocity and the condenser geometry. There may be experimental correlations of heat...

Can the fibers slide at the crossovers or are they locked?

No. The 32.2 is fixed. And the measured force at the equator would be < 1 lb.

Maybe they counted the water of hydration as part of the total water.
