ln(y) +y = ln(x) + x +C y=?

Ok, thank you. So, am I saying something right if I said that P1 = Patm + air density * gravity* h1? Or could I assume that the P1 = Patm?

So I can write Patm hinitial = P2 (0.25-h) where h is the heigh of compressed air. Me doubt is what is hinitial? Can I Convert the 75cm Hg to cm of air?

NEW Kuruman thank you for your answer. h1 and h2 are the length of left and right arm respectively. So, how can I solve the problem with ideal gas law? thank you

Homework Statement A J-shaped tube has an uniform cross section and it contains air to atmosphere pression of 75 cmo of Hg. It is pours mercury in the right arm, this Compress the closed air in the left arm. Which is the heigh of the mercury's column in left arm when the right arm is full of...

Homework Statement A rectangular weir (Cd = 0.623) thin crest without lateral contraction of 1 meter in length and a triangular weir (theta = 90 °) are located on the same channel. If the apex of the triangular weir (Cd = 0.593) is 0.15 meters below the crest of the rectangular weir and...

Thank you

Thank you, I got this too, when I put the origin in the base of the tank

I think I understand, but there are some exercises in which is valid to take the zero down or away from the element considered. For example in this exercise (strain energy) and I only integrate in the real part of the element. So when will know whether it is valid or not take away the element...

I have surface area =20 H, because the length of 20 is constant. And from the relation between triangles I know that X=H

Homework Statement A deposit of 20 feet long and 10 feet high, has a width of 8 feet at the bottom and 18 feet at the top. In the bottom is an orifice an area of 24 in2 and discharge coefficient of 0.60. If the tank is full calculate the time required for the lower level 6 feet. Consider full...

Homework Statement In the figure are the dimensions, and the question is the time in which the take will empty Area of orifice 1 cm2 Discharge coefficient: 0.447 Gravity 10 m/s2 Homework Equations [/B] Area of surface = 8x = 8 (2 H) = 16H The Attempt at a Solution . The red lines are the...

Homework Statement Calculate "H" Homework Equations Bernoulli Manometry The Attempt at a Solution I have calculated that Q=0.06723 m^3 /s If I apply Bernoulli in the surface of the tank A and in out of the pipe, I have: H =(velocity in the final part of the pipe^2)/(2g). I have assumed that...

Thank you

Ok, thank you for correcting my grammar. It's true, I have 2 questions
