Mechanical Energy Balance for Fluids

Pipelines 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.

Thanks Proff, Pangmalakasan example... This video is really helpful

THANKYOUU SO MUCHHH!

Very helpful!

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

Thanks for the corrections.

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

[@apm]

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.

[@rafaelgodinez3631]

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.
