Answer:
11.125°
Explanation:
Given:
Radius of bend, R = 100 m
Speed around the bend = 50 Km/hr = = 13.89 m/s
Now,
We have the relation
where,
θ = angle of banking
g is the acceleration due to gravity
on substituting the respective values, we get
or
or
θ = 11.125°
Answer:
The power input, in kW is -86.396 kW
Explanation:
Given;
initial pressure, P₁ = 1.05 bar
final pressure, P₂ = 12 bar
initial temperature, T₁ = 300 K
final temperature, T₂ = 400 K
Heat transfer, Q = 6.5 kW
volumetric flow rate, V = 39 m³/min = 0.65 m³/s
mass of air, m = 28.97 kg/mol
gas constant, R = 8.314 kJ/mol.k
R' = R/m
R' = 8.314 /28.97 = 0.28699 kJ/kg.K
Step 1:
Determine the specific volume:
p₁v₁ = RT₁
Step 2:
determine the mass flow rate; m' = V / v₁
mass flow rate, m' = 0.65 / 0.81997
mass flow rate, m' = 0.7927 kg/s
Step 3:
using steam table, we determine enthalpy change;
h₁ at T₁ = 300.19 kJ /kg
h₂ at T₂ = 400.98 kJ/kg
Δh = h₂ - h₁
Δh = 400.98 - 300.19
Δh = 100.79 kJ/kg
step 4:
determine work input;
W = Q - mΔh
Where;
Q is heat transfer = - 6.5 kW, because heat is lost to surrounding
W = (-6.5) - (0.7927 x 100.79)
W = -6.5 -79.896
W = -86.396 kW
Therefore, the power input, in kW is -86.396 kW

The output will be (3, 4) becomes (8, 10)
Explanation:
#include <stdio.h>
//If you send a pointer to a int, you are allowing the contents of that int to change.
void CoordTransform(int xVal,int yVal,int* xNew,int* yNew){
*xNew = (xVal+1)*2;
*yNew = (yVal+1)*2;
}
int main(void) {
int xValNew = 0;
int yValNew = 0;
CoordTransform(3, 4, &xValNew, &yValNew);
printf("(3, 4) becomes (%d, %d)\n", xValNew, yValNew);
return 0;
}
Answer:
Explanation:
From the question we are told that:
Voltage
Power
Initial Power factor
Final Power factor
Generally the equation for Reactive Power is mathematically given by
Q=P(tan \theta_2-tan \theta_1)
Since
And
Therefore
Therefore
The size of the capacitor in vars that is necessary to raise the power factor to 0.9 lagging is
Answer:
Explanation:
Adjusting the distance between the two electrodes is called gapping your spark plugs. You need a feeler gauge to gap your spark plugs properly If you're re-gapping a used plug, make sure that it's clean (gently scrub it with a wire brush)
hope this you
