Answer:0.1898 Pa/m
Explanation:
Given data
Diameter of Pipe![\left ( D\right )=0.15m](https://tex.z-dn.net/?f=%5Cleft%20%28%20D%5Cright%20%29%3D0.15m)
Velocity of water in pipe![\left ( V\right )=15cm/s](https://tex.z-dn.net/?f=%5Cleft%20%28%20V%5Cright%20%29%3D15cm%2Fs)
We know viscosity of water is![\left (\mu\right )=8.90\times10^{-4}pa-s](https://tex.z-dn.net/?f=%5Cleft%20%28%5Cmu%5Cright%20%29%3D8.90%5Ctimes10%5E%7B-4%7Dpa-s)
Pressure drop is given by hagen poiseuille equation
![\Delta P=\frac{128\mu \L Q}{\pi D^4}](https://tex.z-dn.net/?f=%5CDelta%20P%3D%5Cfrac%7B128%5Cmu%20%5CL%20Q%7D%7B%5Cpi%20D%5E4%7D)
We have asked pressure Drop per unit length i.e.
![\frac{\Delta P}{L} =\frac{128\mu \ Q}{\pi D^4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5CDelta%20P%7D%7BL%7D%20%3D%5Cfrac%7B128%5Cmu%20%5C%20Q%7D%7B%5Cpi%20D%5E4%7D)
Substituting Values
![\frac{\Delta P}{L}=\frac{128\times8.90\times10^{-4}\times\pi \times\left ( 0.15^{3}\right )}{\pi\times 4 \times\left ( 0.15^{2}\right )}](https://tex.z-dn.net/?f=%5Cfrac%7B%5CDelta%20P%7D%7BL%7D%3D%5Cfrac%7B128%5Ctimes8.90%5Ctimes10%5E%7B-4%7D%5Ctimes%5Cpi%20%5Ctimes%5Cleft%20%28%200.15%5E%7B3%7D%5Cright%20%29%7D%7B%5Cpi%5Ctimes%204%20%5Ctimes%5Cleft%20%28%200.15%5E%7B2%7D%5Cright%20%29%7D)
=0.1898 Pa/m
A question the design team should answer before handing off the designs is: are the designs a true representation of the intended end user experience?
<h3>What is a website?</h3>
A website can be defined as a collective name that is used to describe series of webpages that are interconnected or linked together with the same domain name.
In Computer technology, the main goal of a high-fidelity prototype is to understand how end users would interact with a website and areas to improve the design.
In conclusion, the design team should answer whether or not the designs are a true representation of the intended end user experience before handing off the designs.

Answer:
power = 49.95 W
and it is self locking screw
Explanation:
given data
weight W = 100 kg = 1000 N
diameter d = 20mm
pitch p = 2mm
friction coefficient of steel f = 0.1
Gravity constant is g = 10 N/kg
solution
we know T is
T = w tan(α + φ )
...................1
here dm is = do - 0.5 P
dm = 20 - 1
dm = 19 mm
and
tan(α) =
...............2
here lead L = n × p
so tan(α) =
α = 3.83°
and
f = 0.1
so tanφ = 0.1
so that φ = 5.71°
and now we will put all value in equation 1 we get
T = 1000 × tan(3.83 + 5.71 )
T = 1.59 Nm
so
power =
.................3
put here value
power =
power = 49.95 W
and
as φ > α
so it is self locking screw
