To give you an idea of what Solucionario Juan Saldarriaga Hi can do for you, here are some examples of problems and solutions that you can find on the website. These are taken from Chapter 2: Pipe Flow.
Problem 2.1: A pipe of diameter D = 0.15 m carries water at a flow rate of Q = 0.05 m3/s. The pipe has a length of L = 100 m and a roughness of e = 0.0015 m. Determine the head loss due to friction and the pressure drop in the pipe.
Solution 2.1: To solve this problem, we need to use the Darcy-Weisbach equation for head loss due to friction:
hf = f (L/D) (V/2g)
where f is the friction factor, L is the pipe length, D is the pipe diameter, V is the average velocity, and g is the gravitational acceleration.
To find the friction factor, we need to use the Colebrook equation:
1/sqrt(f) = -2 log10 [(e/D)/3.7 + 2.51/(Re sqrt(f))]
where e is the pipe roughness, D is the pipe diameter, and Re is the Reynolds number.
To find the Reynolds number, we need to use the definition:
Re = VD/v
where V is the average velocity, D is the pipe diameter, and v is the kinematic viscosity of water.
To find the average velocity, we need to use the continuity equation:
V = Q/A
where Q is the flow rate and A is the cross-sectional area of the pipe.
Now we have all the equations that we need to solve this problem. We can plug in the given data and solve for the unknowns using a calculator or a spreadsheet. The results are:
V = 0.05 / (pi * 0.15/4) = 2.82 m/s
A = pi * 0.15/4 = 0.0177 m
v = 1.004 * 10 m/s (at 20ÂC)
Re = 2.82 * 0.15 / (1.004 * 10) = 421000
f = 0.019 (solving the Colebrook equation iteratively)
hf = 0.019 * (100/0.15) * (2.82/2*9.81) = 5.67 m
The head loss due to friction is 5.67 m.
To find the pressure drop in the pipe, we need to use the Bernoulli equation:
p1/gamma + z1 + V1/2g = p2/gamma + z2 + V2/2g + hf
where p is the pressure, gamma is the specific weight of water, z is the elevation, V is the velocity, and hf is the head loss due to friction.
If we assume that the pipe is horizontal and that the velocity is constant along the pipe, then we can simplify this equation as:
p1/gamma - p2/gamma = hf
The pressure drop in the pipe is then:
p1 - p2 = gamma * hf
p1 - p2= 9810 * 5.67 = 04f6b60f66
