Answer:
the given statement is true.
Explanation:
Answer:
X_cp = c/2
Explanation:
We are given;
Chord = c
Angle of attack = α
p u (s) = c 1
p1(s)=c2,
and c2 > c1
First of all, we need to find the resultant normal force on the plate and the total moment about leading edge.
I've attached the solution
Answer:
The heat transferred to water equals 1600 kJ
Explanation:
By the conservation of energy we have
All the kinetic energy of the moving vehicle is converted into thermal energy
We know that kinetic energy of a object of mass 'm' moving with a speed of 'v' is given by
Thus
Thus the heat transferred to water equals
Answer:
209.55 ft
Explanation:
Given Data:
Benchmark:
Reduced Level or Elevation = 210.50
Height of Instrument = Reduced Level + Back sight Reading
Height of Instrument = 210.50 + 3.57 = 214.07 ft
Turning Point:
Back sight Reading = 2.91 ft
Fore Sight Reading = 4.52
Reduced Level or Elevation of Turning Point = Height of Instrument – fore sight Reading
Reduced Level or Elevation of Turning Point = 214.07 – 4.52 = 209.55 ft
Height of Instrument at Turning Point = Reduced Level + Back sight Reading
Height of Instrument at Turning Point = 209.55 + 2.91 = 212.46 ft
