Answer:
The Reynold Number is 146415.34
Explanation:
The density of ethyl alcohol = ρ = 789 kg/m^3
The dynamic viscosity of ethyl alcohol = μ = 0.001095 kg/m.s
Velocity = V = 4 m/s
Diameter of pipe = D = 2 in = 0.0508 m
The Reynold's number (Re), will be:
Re = ρVD/μ
Re = (789 kg/m^3)(4 m/s)(0.0508 m)/(0.001095 kg/ms)
<u>Re = 146415.34</u>

Answer:
Explanation:
A system is known to be a stable system if the poles of the system lie on the negative real axis of the s plane.
A system that could be driven unstable by a P-controller would be:
As the value of K increases, the closed loop poles move into the right half s plane
Answer / Explanation:
Eavesdropping attack is also sometimes refereed to as sniffing attack. It is simply the process by which an attacker or hacker tries to penetrate very suddenly into an unaware individuals network or server with the intention to steal information transmitted over the network or server through that computer.
To prevent such attack, there are several mean which include installing network monitoring software to check who else is connected to the network but the most common method of preventing such attack is to encrypt the Hypertext Transfer Protocol (http) and the way to do this is by securing it with a sort of security key.
On installing the security key, the network becomes encrypted and secured such that whatever network transmitted over the network becomes encrypted and unable to read. The protocol then converts to (https).
