Answer:
How do I calculate voltage drop?
To calculate voltage drop, E, across a component, you need to know the resistance of the component and the current thru it. Ohm's Law is E=I⋅R , which tells us to then multiply I by R . E is the voltage across the component also known as voltage drop
Explanation:
a pipe discharges wine into a 1.5m diameter tank. Another pipe (15cm diameter), located near the base of the, is used to discharge wine out of the tank. Calculate the volumetric flow rate into the tank if the wine level remains constant at 2.5m.
The volumetric flow rate into the tank if the wine level remains constant at 2.5m is; 0.1232 m³/s
How to Calculate Volumetric Flow Rate?The formula for volumetric flow rate is;
V' = area * velocity
We are given;
Diameter; d = 15 cm = 0.15 m
Thus;
Area; A = (π/4)d²
A = (π/4)(0.15)²
A = 0.0176 m²
Velocity is; v = √(2gh)
v = √(2 * 9.8 * 2.5)
v = 7 m/s
Thus volumetric flow rate is;
V' = 0.0176 * 7
V' = 0.1232 m³/s

A group of friends that are identical in every manner would prevent opportunities for personal development and learning, but having friends with similar interests and values might foster a feeling of community and shared experiences.
Thus, Lack of diversity would limit opportunities for new viewpoints, original ideas, and varied experiences. There might not be enough intellectual and emotional stimulation and repetitious conversations and exchanges.
Because everyone would address problems and obstacles in the same way, life might become predictable and static.
Although conflicts and disagreements may be less frequent, the lack of diverse opinions may make it more difficult to come up with original solutions.

If a 1500 V load is ac coupled to the output in Figure 9–60, what is the resulting output voltage (rms) when a 50 mV rms input is applied? gm = 5000 mS.
The resulting output voltage (rms) when a 50 mV rms input applied is -187.5 mV.
What is rms voltage?Root Mean Square Voltage is the amount of AC power which produces the same heating effect as DC Power would have produced.
Vo = -gm x Vi (Rd II Rl )
Vo = -5000 x 10⁻⁶ x 50 x 10⁻³ x (1.5k II 1.5k )
Vo = -25 x 10⁻² x 750 x 10⁻³
Vo = -187.5 mV

The maximum shear stress in the tube when the power is transmitted through a 4: 1 gearing is 28.98 MPa.
What is power?Power is the energy transferred per unit time.
Torque is find out by
P = 2πNT/60
10000 = 2π x 2000 x T / 60
T =47.74 N.m
The gear ratio Ne / Ns =4/1
Ns =2000/4 = 500
Ts =Ps x 60/(2π x 500)
Ts =190.96 N.m
Maximum shear stress τ = 16/π x (T / (d₀⁴ - d₁⁴))
τ max =T/J x D/2
where d₁ = 30mm = 0.03 m
d₀ = 30 +(2x 4) = 38mm =0.038 m
Substitute the values into the equation, we get
τ max = 16 x 190.96 x 0.038 /π x (0.038⁴ - 0.03⁴)
