AI Thread Summary
To convert 20mm of gas to pascals, additional information is required, specifically the density of the gas and the acceleration due to gravity. The formula to use is p = hρg, where p is pressure in pascals (N/m²), h is the height in meters, ρ is the density in kg/m³, and g is the acceleration due to gravity (approximately 9.81 m/s²). Without knowing the gas density, a direct conversion cannot be completed. Understanding these variables is crucial for accurate pressure calculations. Proper application of the formula will yield the pressure in pascals.

i know this probably sounds really stupid but how do i convert 20mm of gas into pascals?
thnx

Pa has units of N/m^2 thus you need a little more info to convert 20mm of gas to pascals.
 
p = h \rho g, when you use SI units in the RHS, P is in N/m^2. You need to know the density of the gas. g is the accelaration of gravity.
 
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...
