Pressure and depth in a static fluid

AI Thread Summary
The discussion focuses on calculating the absolute pressure in a meat baster bulb based on the height of the basting sauce. The formula used is Pbaster = Pair - dgH, where Pair is the atmospheric pressure, d is the density of the sauce, g is the acceleration due to gravity, and H is the height of the sauce column. For a height of 0.17 m, the calculated pressure is approximately 98917.62 Pa, while for 0.10 m, it is around 99898.6 Pa. These calculations demonstrate how pressure changes with varying fluid heights in a static fluid system. Understanding these principles is essential for applications involving fluid dynamics in everyday tools.

A meat baster consists of a squeeze bulb attached to a plastic tube. When the bulb is squeezed and released, with the open end of the tube under the surface of the basting sauce, the sauce rises in the tube to a distance h, as the drawing shows. Using 1.013 × 1055Pa for the atmospheric pressure and 1430 kg/m3 for the density of the sauce, find the absolute pressure PB in the bulb when the distance h is (a) 0.17 m and (b) 0.10 m.

Pbaster = Pair - dgH
Pbaster = 1.013 x 105 - 1430(9.8)(0.17) = 98917.62 Pa?

and second Pa is Pa = 99898.6 Pa?

That looks good to me.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
