An engineer is applying dimensional analysis to study the flow of air through this horizontal sudden contraction for the purpose

of characterizing the pressure drop. The flow is being modeled as constant density and steady. What is the functional relationship of the variables that characterize this situation

Answer:

The answer is " \Delta p = f(V1, p, V2, d, D, L)"

Explanation:

Please find the complete question in the attached file.

Its change in temperature in pipes depends on rate heads and loss in pipes owing to pipe flow, contractual loss, etc.

The temperature change thus relies on V1 v2 p d D L.

How did ancient machines pave the way for improvement
Leno4ka [110]

Answer:

----------

Explanation:

Ancient machines have paved the way for improvement by being the foundation for change. these machines made it possible to find flaws so in the next generations, they could fix, develop, and produce better quality machines. eventually this process has reached the present time but after today, the process will continue to produce even better quality machines than the time before. I hope this helps!

A missile flying at high speed has a stagnation pressure and temperature of 5 atm and 598.59 °R respectively. What is the densit
alexdok [17]

Answer:

5.31\frac{kg}{m^3}

Explanation:

Approximately, we can use the ideal gas law, below we see how we can deduce the density from general gas equation. To do this, remember that the number of moles n is equal to \frac{m}{M}, where m is the mass and M the molar mass of the gas, and the density is \frac{m}{V}.

For air M=28.66*10^{-3}\frac{kg}{mol} and \frac{5}{9}R=K

So, 598.59 R*\frac{5}{9}=332.55K

pV=nRT\\pV=\frac{m}{M}RT\\\frac{m}{V}=\frac{pM}{RT}\\\rho=\frac{pM}{RT}\\\rho=\frac{(5atm)28.66*10^{-3}\frac{kg}{mol}}{(8.20*10^{-5}\frac{m^3*atm}{K*mol})332.55K}=5.31\frac{kg}{m^3}

Determine ten different beam loading values that will be used in lab to end load a cantilever beam using weights. Load values sh
nasty-shy [4]

Answer:

1st value = 1.828 * 10 ^9 gm/m^2 -------     10th value = 7.312 * 10^9 gm/m^2

Explanation:

initial load ( Wp) = 200 g

W1 ( value by which load values increase ) = 100 g

Ten different beam loading values :

Wp + w1 = 300g ----- p1

Wp + 2W1 = 400g ---- p2

Wp + 3W1 = 500g ----- p3 ----------------- Wp + 10W1 = 1200g ---- p10

x = 10.25" = 0.26 m

b = 1.0" = 0.0254 m

t = 0.125" = 3.175 * 10^-3 m

using the following value to determine the load values at different beam loading values

attached below is the remaining part fo the solution
