Answer:
Explanation:
An expression was assumed for E(V) = av^2 + bv + c
each values for substituted for corresponding values of the velocity and a three unknown equation was formed, which was solved simultaneously to get the three unknowns (a, b and c).
The unknowns was substiutted back ito the original equation.
Answer:
The line voltage of the three phase network is 346.41 V
Explanation:
Star Connected Load
Resistance, R₁ = R₂ = R₃ = 18 Ω
For a star connected load, the line current = the phase current, that is we have
Whereby the the voltage across each resistance = is given by the relation;
=
× R
Hence;
=
=
× R = 25 × 8 = 200 V
Therefore we have;
The line voltage, = √3 ×
= √3 × 200 = 346.41 V.
Hence, the line voltage of the three phase network = 346.41 V.
Answer:
0.506N
Explanation:
In this question, we are asked to calculate the total drag force on a plate which is oriented parallel to an air flow at a particular temperature and atmospheric pressure.

Answer:
Stat PVC = Stat(82+98.5)
Stat PVT = Stat(59+71.5)
Explanation
PVI = 71 + 35
Let G1 = Grade 1; G2 = Grade 2
G1 = +2.1% ; G2 = -3.4%
Highest point of curve at station = 74 + 10
General equation of a curve:
At highest point of the curve
