Recently, Toyota held a 'press drive' day for their 2016 Prius and Jason of Jalopnick had the good sense to make a video of the speedometer during a maximum acceleration. I downloaded the video and coded the timestamps of each speed change to generate this curve: This confirmed the 0-60 is...

I see it and that makes sense. The volume will increase because of the temperature but with only one degree of freedom, altitude, that becomes the sea level rise. In effect, analysis of one element of the ring. Thanks, Bob Wilson

Correct but I had taken out the land mass, the slope of the shore. Adding a sloped shore is the type of buffer needed to moderate the sea level rise. In the real world, heating a solid, especially one with poor tensile strength and thermal conductivity, can lead to fractured surfaces. In the...

We agree I'm calculating what happens to the heated surface layer. Descriptive Physical Oceanography, An Introduction, Talley, L.D. Pickard, George L., Emery, William J., Switft, James H. indicates the solar induced heating primarily occurs in the first meter. Heating at lower levels comes from...

Here is my spreadsheet. This approach dates back to a 1970, material course where we calculated the dimension changes of a hollow sphere and solid ball of the same diameter. So reducing the Earth's sea surface to a ring seemed an acceptable approach. Just the results suggest I've either done...

I double-checked my excel spreadsheet and don't see an obvious error. The most complex calculations are surface area: H1 - Earth radius in meters =4*PI()*H1*H1 # Earth sea surface area, H1 = Earth radius in meters, H3 = 71% of Earth sea surface area =POWER(H3/(4*PI()),0.5) # converting...

Homework Statement I am attempting to replicate the IPCC estimates of the amount of sea level rise due to thermal effects on the seawater. The earth, black-body temperature is 16C but there are projections of a 1C increase in less than 100 years. Ignoring ice melt and land flooding, how much...

Perhaps the motor bearings should be included? I don't see a shaft coupler to handle alignment errors . . . unless the motor rotor is built as integral to the flywheel shaft. I'm not familiar with the software as much as what bad things happen when these elements are . . . neglected. GOOD...

That is one of the reasons why this prototype is important. Sad to say, it is difficult to find the performance specs for turbines. I did find mass-flow, efficiency charts for the turbo charger I'd bought several years ago but my best case estimate including injecting enough water for 20 kW...

Uh, my prototype is exploiting the waste heat in the exhaust gas. In the Prius, there is no belt driven alternator. I think you are analyzing a traditional vehicle, not a Toyota hybrid electric. My 2003 Prius only has one belt and it runs the air conditioner compressor and engine water pump...

Curiously, I have been interested in this subject for several years and just started a prototyping effort: So I bought a turbo-charger a couple of years ago and finally started blue-printing it: I'm building a brass-board based upon a 1.4kW rated, brushless motor normally used for...
