I'm reworking it but I'm only using the units I gave simply because the answer is in ft/s, so I've converted the Area from inches to ft as well, or rather the diameter. I will respond my attempt shortly. However, I do understand that under normal circumstances 9.81 m s-2 is used, so I assume...

Y is the specific weight of water, which is either 9.81kN/m3 or 62.4 lb/ft3 in this case I am using the 62.4.

So far I have Vb = SQRT(Va^2+(Pa-Pb/y)) Which I know all of except Va and I have Va=Vb*(Ab/Aa) Which leaves me clueless.. even though I have 2 separate equations.. I guess I have the flow rate equation which can either be Va = Qa/Aa or Vb = Qb/Ab but Q cannot be solved because I cannot...

Vb is what is being looked for, Va is unknown, however.

Homework Statement For the pipe reducer shown in Figure 6.27 in your textbook, the pressure at point A is 45.8 psig and the pressure at B is 39.5 psig. Calculate the velocity of flow, in ft/s, of the water at point B. State your answer to one decimal place. Example: 25.6 Homework...

Homework Statement Mildred pulls a sled loaded with beer along a horizontal surface at constant velocity, as Bubba told her he needed it for he and his buddies to watch the football game. If the sled and beer in it has mass = 75 kg, the coefficient of kinetic friction μk between the runners...

So I write the Equation.. m_2 = -138 + m_2g -------------------- 2 However, I still scratch my head at this, and I'm not sure if substituting would work either. Sorry if my algebra skills seem to be lacking... it is 1:37 a.m. where I am at currently.

Homework Statement A 20.0 kg block rests on a frictionless inclined plane of slope angle 30.0 degrees. A light cord attached to the block passes over a frictionlesss pulley at the top of the plane and is attached to a second block. What must be mass of the second block if the system is to be...

Well since the trooper was 4 seconds late, you would still have to subtract 4 seconds, so the answer would be 33.6s because it's (t-4)

I see.. I had no idea about the simple step of multiplying 4 seconds, blew my mind haha. 120 + 30t = t^2 0 = T62 - 30t - 120 x=33.57417562100671 x=−3.5741756210067095 obviously the answer is 33.6

v0t + ½*at^2 = v0t + ½*a(t+5)^2 0 = + t^2 - 30 m/s*t + 25 This might be crazy but this does not work I know that much lol I set the last equation but added +5 because the trooper had a 5 second loss.. I just feel like I'm missing something so simple. I'm not getting any of these answers...

x =v0t + ½*at 2 but V0 = 0 so it would just be x = .5*at, but that would be 2 unknowns (time, and displacement)

Homework Statement Cletus is traveling at 30.0 m/s as he passes a trooper hidden behind a billboard. Four seconds later, the trooper begins his chase for Cletus with a constant acceleration of 2.00 m/s2. How long does it take the trooper to intercept Cletus? Homework Equations x...

Homework Statement James Gomer holding a uniform 40 N rod of length 1 m horizontally with a hinge on its left end and a vertical string on the right end. Now suppose a fully laden swallow with a mass of 2.00 kg lands and squawks loudly on the rod at a point 30.0 cm to the right of the hinge...

Homework Statement Harold has a mass of 72.2 kg, and is standing on a scale in an elevator cab. What will the scale read if the elevator is moving downwards at a constant 0.050 m/s?Homework Equations The Attempt at a Solution Since the scale has a normal force upward and Harold has an...
