Answer:
r=0.31
Ф=18.03°
Explanation:
Provided:
Original diameter of bar = 75 mm
Diameter post-cutting = 73 mm
Average diameter of the bar d= (75+73)/2=74 mm
Average length of uncut chip = πd
Average length of uncut chip = π x 74 =232.45 mm
Thus, cutting ratio r
r=0.31
Therefore, the cutting ratio equals 0.31.
Now, the shearing angle is given as
Next by substituting the values
\
Ф=18.03°
Concluding, the shearing angle is 18.03°.
Answer:
The resolution for this question is below in the explanation section.
Explanation:
The right response to this question is A, which is 112002.
The correct code relating to this question is presented below
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
//#include "csapp.h"
void end(void)
{
printf("2");
}
int main()
{
if (fork() == 0)
atexit(end);
if (fork() == 0)
printf("0");
else
printf("1");
exit(0);
}
/* $end forkprob2 */
When this program is executed, the fork function will yield varying results.
However, it should be noted that running it multiple times will produce inconsistent values. The most common output the program will generate is A.
Attached is an image of the program's execution for further clarification.
Answer:
The power of the pump is 23.09 kW.
Explanation:
Parameters
gravitational constant,
mass flow rate,
flow density,
efficiency of the pump,
output gauge pressure,
input gauge pressure,
cross-sectional area of output pipe,
cross-sectional area of input pipe,
height of discharge, (evaluated at pump’s maximum height of 1.22 m)
input height,
hydraulic power of the pump,
Initially, the volumetric flow (Q) needs to be determined
Next, compute the velocity (v) for both input and output
Subsequently, the total head (H) can be calculated
Finally, the computation of pump power is done as follows
