Answer:
Diffie Hellman key exchange.
Explanation:
Diffie Hellman key exchange :
This is the technique which is used to exchanging cryptographic keys in the public channel.This is also represent as DH keys.This is the first public key protocol.This keys given by Diffie and Hellman.These keys enable two users to exchange a secret key securely .
So the answer is Diffie Hellman key exchange.
Answer:
The velocity at R/2 (midway between the wall surface and the centerline) is given by (3/4)(Vmax) provided that Vmax is the maximum velocity in the tube.
Explanation:
Starting from the shell momentum balance equation, it can be proved that the velocity profile for fully developedblaminar low in a circular pipe of internal radius R and a radial axis starting from the centre of the pipe at r=0 to r=R is given as
v = (ΔPR²/4μL) [1 - (r²/R²)]
where v = fluid velocity at any point in the radial direction
ΔP = Pressure drop across the pipe
μ = fluid viscosity
L = pipe length
But the maximum velocity of the fluid occurs at the middle of the pipe when r=0
Hence, maximum veloxity is
v(max) = (ΔPR²/4μL)
So, velocity at any point in the radial direction is
v = v(max) [1 - (r²/R²)]
At the point r = (R/2)
r² = (R²/4)
(r²/R²) = r² ÷ R² = (R²/4) ÷ (R²) = (1/4)
So,
1 - (r²/R²) = 1 - (1/4) = (3/4)
Hence, v at r = (R/2) is given as
v = v(max) × (3/4)
Hope this Helps!!!
Answer:
<em>The output will be (3, 4) becomes (8, 10)
</em>
Explanation:
#include <stdio.h>
<em>//If you send a pointer to a int, you are allowing the contents of that int to change.
</em>
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:
The number of kilo- grams of hydrogen that pass per hour through this sheet of palladium is 
Explanation:
Given
x1 = 0 mm
x2 = 6 mm = 6 * 
m
c1 = 2 kg/
c2 = 0.4 kg/
T = 600 °C
Area = 0.25 
D = 1.7 * 
First equation
J = - D 
Second equation
J = 
To find the J (flux) use the First equation
J = - 1.7 * * 
To find M use the Second equation
= 
M =
Answer:
exit temperature 285 K
Explanation:
given data
temperature T1 = 270 K
velocity = 180 m/s
exit velocity = 48.4 m/s
solution
we know here diffuser is insulated so here heat energy is negleted
so we write here energy balance equation that is
0 = m (h1-h2) + m × 
.....................1
so it will be
.....................2
put here value by using ideal gas table
and here for temperature 270K
h1 = 270.11 kJ/kg
solve it we get
h2 = 285.14 kJ/kg
so by the ideal gas table we get
T2 = 285 K
