    Hose Speed Water
AI Thread Summary
To calculate the speed of water through a hose with a diameter of 2 cm filling a 20 L bucket in 1 minute, the flow rate formula (flow rate = area × velocity) is essential. The area of the hose's cross-section must be used to determine the velocity, which was initially confused with the bucket's area. After recalculating, a speed of 1.06 m/s was obtained, which is a valid result for this scenario. However, the discussion highlights the need for clarity on pressure values in Bernoulli's equation, which remains unresolved. Understanding the correct application of flow rate and area is crucial for accurate calculations.

Homework Statement



A water hose 2 cm in diameter is used to fill a 20 L bucket. If it takes 1 min to fill the bucket, what is the speed at which the water moves through the hose ( note 1L= 1000cm^3)

Homework Equations


Bernoulli's equation
P1+.5pv^2+pgh1=P2+.5pv^2+pgh2

The Attempt at a Solution


I tried to plug various numbers in, however the problem is unspecific and i am stuck on how to find pressures 1 and 2. can someone explain this to me?

Have you tried the equation flow rate=Av?
 
Yeah after i posted this question i looked through the book and found that formula... but i used it for the area of the base of the hoseis rather than the bucket and got 1.06 m/s... is that okay?
 

Thread 'Errors and significant figures'

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 '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...
