Calculating Gauge Pressure Have I worked it correctly?

AI Thread Summary
To calculate the gauge pressure required to compress pure water from 1.000 L to 989 mL, the bulk modulus of water (2.2 x 10^9 N/m^2) can be used with the formula B = delta P/(delta v)/v. The discussion also seeks to determine the height of a steel bar needed to exert this pressure, with the bar's density provided. A user noted that the original poster had posted the same question multiple times across forums, indicating a lack of clarity in their request for help. The conversation emphasizes the importance of providing clear information and engaging constructively for effective assistance.

Simple Gauge Pressure Question

(a) Calculate the gauge pressure (it does not include atmosphereric P) required to compress pure water from 1.000 L to 989 mL. Give an answer in both N/m^2 and psi, lb/in^2.

(b) What height in meters and feet of a 1x1 cm^2 steel bar (density=7.86 g/cm^3) is required to exert the pressure found in part (a)?

Avoid multiple postings

Hi, you seem to have posted the same question three times in different forums. I had given you an answer yesterday. If you didn't find my answer helpful. you could have just said so and others would have come forward to help you. Here's what I'd written.

==========================================
a. Use the formula for bulk modulus. B = delta P/(delta v)/v. B for water is 2.2*10^9 N/m^2.

I hope the other answers will follow.
==========================================

Where are you getting stuck?

Oh, I see that you have enclosed your work. We'll see it as soon as it's clear for approval.

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
