OHH,... so what you are saying is that I use previously acquired volume of .00398 in this eq. I am sorry if I am frustrating. I mean well! OH no... do I convert 7.84 g/cm^3 to kg/m^3 ?? if so 7.84 g/cm^3 (100cm*100cm*100cm) * 1kg = 7840 kg/m^3...

**semantics making Bernoulli's Eq KILLER! see if you can make sense Homework Statement a pipe that carries a fluid ρ = 873 kg/m3 lies along the slope of a smooth hill which is 140 m high. The speed of the liquid at the bottom of the hill is 6.5 m/s. The diameter of the crude oil pipe line at...

-38.96 (which can't be right) *rather than /38.96

ok, a little hazy. Fw(water) is 39N=dens water*v*g? than V = .00398 if so, Fw(water)-39N=Fw (air) than Fw(air) is /38.96??

a pipe that carries a fluid ρ = 873 kg/m3 lies along the slope of a smooth hill which is 140 m high. The speed of the liquid at the bottom of the hill is 6.5 m/s. The diameter of the crude oil pipe line at the top of the hill reduces by a factor 5. Please answer the following: Hint (a) By...

hi, thanks so much! i got that one... will you look at this one? I feel like I am so close. https://www.physicsforums.com/showthread.php?p=2286412#post2286412 OR A chunk of carbon steel with density, ρ = 7.84 g/cm3 , is completely submerged in fresh water. The chuck of steel weighs 39...

Homework Statement A chunk of carbon steel with density, ρ = 7.84 g/cm3 , is completely submerged in fresh water. The chuck of steel weighs 39 N more in air than in water. Please answer the following: (a) Find the buoyant force acting on the chuck of steel. N (b) Find the the...

4e/1x?? or 1e/4x

I used L 10 on Earth and planet X and got T = 6.34 on earth, then doubled it and solved for X grav and got 2.4525 resulting in 2.587:1 which isn't right. i did the same thing with L 50 on Earth and got a different ratio... ehhhkkk!

doppler effect quick question! Homework Statement An ambulance traveling at speed 31 m/s is producing a loud sound of frequency 895 Hz. You see the ambulance in your rear view mirror as the ambulance approaches you and you slow down to 14 m/s as a law obeying citizen (hehehe we know now)...

Homework Statement Now you take off to an unknown planet with the same pendulum as in part (a). You measure the period of the pendulum on that planet and you find it to be twice as much compared to the one of the pendulum while on Earth. What is the ratio of ge on Earth to the gx of the...

hi, this is very confusing. the question is A horizontal water main with a cross-sectional area of 220 cm2 necks down to a pipe of area 55 cm2. Meters mounted in the flow on each side of the transition coupling show a change in gauge pressure of 85 kPa. Determine the flow rate...

Homework Statement A horizontal water main with a cross-sectional area of 220 cm2 necks down to a pipe of area 55 cm2. Meters mounted in the flow on each side of the transition coupling show a change in gauge pressure of 85 kPa. Determine the flow rate through the system, taking the fluid to...
