Answer:
Mechanical Efficiency = 83.51%
Explanation:
Given Data:
Pressure difference = ΔP=1.2 Psi
Flow rate = ![V=8ft^3/s\\](https://tex.z-dn.net/?f=V%3D8ft%5E3%2Fs%5C%5C)
Power of Pump = 3 hp
Required:
Mechanical Efficiency
Solution:
We will first bring the change the units of given data into SI units.
![P=1.2*6.895 = 8.274KPa\\V=8*0.00283=0.226 m^3/s\\P=3*0.746=2.238KW](https://tex.z-dn.net/?f=P%3D1.2%2A6.895%20%3D%208.274KPa%5C%5CV%3D8%2A0.00283%3D0.226%20m%5E3%2Fs%5C%5CP%3D3%2A0.746%3D2.238KW)
Now we will find the change in energy.
Since it is mentioned in the statement that change in elevation (potential energy) and change in velocity (Kinetic Energy) are negligible.
Thus change in energy is
![=(Mass * change in P)/density\\= \frac{M*P}{p}\\\\](https://tex.z-dn.net/?f=%3D%28Mass%20%2A%20change%20in%20P%29%2Fdensity%5C%5C%3D%20%5Cfrac%7BM%2AP%7D%7Bp%7D%5C%5C%5C%5C)
As we know that Mass = Volume x density
substituting the value
Energy = Volume * density x ΔP / density
Change in energy = Volumetric flow x ΔP
Change in energy = 0.226 x 8.274 = 1.869 KW
Now mechanical efficiency = change in energy / work done by shaft
Efficiency = 1.869 / 2.238
Efficiency = 0.8351 = 83.51%
The function that you will use in order to test the reverse route back toward the original host is known as Extended ping. Thus, the correct option for this question is B.
<h3>What is Ping and traceroute for?</h3>
Ping and traceroute are the common commands you can effectively utilize in order to troubleshoot network problems. Ping is a simple command that can typically test the reachability of a device on the network. While traceroute is a command you use to 'trace' the route that a packet takes when traveling to its destination.
Extended ping permits a router's ping command to use The router's LAN IP address from within the subnet, fully testing the route back to the subnet. A standard ping often does not test the reverse route that you need to back toward the original host.
Therefore, the function that you will use in order to test the reverse route back toward the original host is known as Extended ping. Thus, the correct option for this question is B.
