anybody here who knows the factor of safety for rotating blades? ASAP. thanks!

it's just typographical error. so is the mixture's SG=0.92?

0.6 (SG of alcohol) + 0.4 (SG of water) = SG of mixture 0.6 (0.8) + 0.4 (1) = SG of mixture SG of mixture = 0.92

i changed my mind, the SG of the solution is 0.92? am i right?

qwer

ok, they are supposed to mix. then will the SG of the alcohol be the SG of the mixture?

Like we can treat the alcohol as oil or any immiscible fluid

i think they are separated since the problem is asking for a height difference.

Homework Statement The fluid in a manometer tube is 40% water and 60% alcohol (specific gravity = 0.8). What is the manometer fluid height difference if a 50kPa pressure difference is applied across the two ends of manometer? Homework Equations P1-P2=50 kPa P3-P2=(ρgh)alc P3-P1=(ρgh)h2o...

HI. :) help me please. when the problems says that there is an allowance stress, especially in thin or thick walled vessels, what kind of stress could it be? thanks!

to my fellow mechanical engineers, please help me with some basic machine design problems. a certain drive shaft rotating at 500 rpm transmits 200 hp to an 8 inch diameter gear. Design a suitable solid shaft for this application. the shaft is ductile. Design stresses are to be limited to...
