9 жыл бұрынPipelines are critical for movement of fuels, water, and other important commodities. This lecture reviews the foundations of a mechanical energy balance. Bernoulli's Equation is a simplification of the mechanical energy balance but with no friction loss or shaft work.

pause 16:44 Using what you have written, I calculate z = -27.45 ft. Can you confirm the calculations?

That doesn't seem correct because the elevation change should be positive.

@@apm sir i am also getting the same answer by calculating the expression.

The work term should be positive. He also forgot to multiply the work term by 32.2 ft/s^2 to cancel out the feet and second units. By making these corrections and solving for Z, you should be able to get the same answer.

A few mistakes I see Mistake 1 Need to multiply the '-ws/m' term by 32.2, which will change it from 333.33 to 10733. Mistake 2 '-ws/m' should be positive Mistake 3 This isn't actually a mistake, but I prefer to do the hp conversion by multiplying by 550 instead of 0.7376/1.34E-3 (550 is much easier to remember and punch into a calculator) good video otherwise, thanks
