Answer:
the flow is turbulent
Explanation:
The Reynolds number is given by
Re=ρVD/μ
where
V=fluid speed=0.48ft/s=0.146m/s
D=diameter=2.067in=0.0525m
ρ=density=0.805g/cm^3=805Kg/m^3
μ=0.43Cp=4.3x10^-4Pas
Re=(805)(0.146)(0.0525)/4.3x10^-4=14349.59
Re>2100 the flow is turbulent
Note: if you do not want to use a calculator you can use the graphs to calculate the Reynolds number according to their properties
Answer:
Hello there, the question is not complete, but not to worry you can check the explanation section to check how you can solve a similar question or to be be able to solve the exact question directly.
Explanation:
The flow of electrons is what is known or refer to as Current. When energy is used on a nuclei, the electrons are forced to move from one position to the other. The direction of flow of electron is from the negative terminal which then moves to the positive terminal.
Therefore, it can be said that the positive charge determines the direction of electron flow. The starting point is the negative terminal, in which it will now move in the direction in which the positive terminal is.
Answer:
120 Hz
Explanation:
Given that a 60 Hz sinusoidal voltage is applied to the input of a half-wave rectifier, what will be the output frequency ?
Ideally, the supply frequency will be equal to the ripple frequency.
But in a half - way rectifier, the out put frequency is twice the input sinusoidal voltage frequency.
The output frequency = 2 × 60
Output frequency = 120 Hz
Therefore, When a 60 Hz sinusoidal voltage is applied to the input of a half-wave rectifier, the output frequency is 120 Hz.
