Answer:
Electromechanical systems or devices are systems or devices that involves the interaction between electrical systems and mechanical systems in which the motion of mechanical parts is converted to electrical energy or made to interact with energy or in which electrical energy is converted to mechanical energy or interacts with a moving mechanical system
Therefore;
Electromechanical systems convert <u>electrical energy</u> input into a <u>mechanical energy</u> output

If there is a random child, you should ask where they should be and where their parents went. if it your child, they prolly want food or sum.
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
