AI Thread Summary
To calculate the pressure at the bottom of the flask containing three distinct liquids, the hydrostatic pressure formula ρgh is applied for each liquid separately. The user initially attempted to sum the pressures from each liquid but was unsure about incorporating atmospheric pressure. The correct approach is to calculate the pressure from each liquid and then add atmospheric pressure to the total at the end, rather than adding it to each individual calculation. This ensures an accurate representation of the total pressure at the bottom of the flask. Clarifying this method is essential for solving the problem correctly.

Liquid 1 with density = 6660 kg/m^3 is poured into cylinder to depth d1 = 70.8 cm; Liq. 2 with density 4995 kg/m^3 is poured on top to a depth of 90cm; and then liquid 3 (density of 1369 kg/m^3) is poured on top of liquid 2 to a depth of 68.5cm). Assuming none of the liquids mix at all what is the pressure at bottom of flask?

I used ρgh for each and added but this is wrong. Should I add the atmospheric pressure to the total?

Any help would be much appreciated..please?
 
Should I add the atmospheric pressure to each calculation or to the total (after adding each (densityxgxh calculation)?
 

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...
