Here is my work here is my work

For the problem attached, I solved it and found the answer for part b : 80.21 s How to get sure or know if the answer is right or not. Thanks

can you show me an example for this if there is available, please!

How to find the dancy friction factor by using the colebrook white equation (not using the moody chart) ; to calculate the 1/√f = -2LOG[(e/d)/3.71 + 2.51/(Re*√f)] help please

For the hydrostatic pressure, when do we use [ p = ρ.g.h ] and [ p = ρ.g.hcg ] where: ρ = density g = acc of gravity h = height of water column hcg = the distance to the center of gravity from the surface of water downward

What is the prove for this formula, or in another way the provement of the dynamic viscosity multiplied by the shear strain will get us the shear stress,

I didn't find it on wikipedia

the equation which is circled

How can I prove this equation: it is attached in a photo.

I have a question I really would be thankful if I had some help For the mix design in the fresh concrete.. I've got the compressive strength 6525 psi, I didn't find it in any table to find the w/c (water-cement ratio), what should I do and if there is a formula for it what it is?

Ahh yes.. Thanks a lot this was really helpful and enough and thanks again for giving me some of your time.

oh thank you this was really helpful.. but now I'm facing a big problem which is how to take the section for a point in a beam for calculating the shearing stress [TAU=V.Q/Ib] or shear flow [q=V.Q/I] .. what is the points that i have to follow to know the section that i have to take for...

In this question below in the 2 files, i have a problem with the ( Q ) in the shearing stress.. can someone help me and explain for me how they get [Q=(32)(30)(15)] for point (a) and how about point (b) also !? what i know that Q=A.y , how did they get (32)(30) for the area and (15) for the...

I need a help and check for my answers.. and i showed you the formula and you said that this formula is right.. but the answers are wrong..
