Answer:
True
Explanation:
The \ is an escape character, is a way to indicate to the compiler that the following characters are special; if you want to print an actual \ you need to use two, one after the other one, in the printf function. But what exactly happens if you try to print just one \
#include <iostream>
using namespace std;
int main()
{
printf ("\");
}
This will produce an error that prevents you from compiling:
main.cpp:15:13: warning: missing terminating " character
printf ("\");
^
main.cpp:15:13: error: missing terminating " character
Answer:
A) m' = 351.49 kg/s
B) m'= 1036.91 kg/s
Explanation:
We are given;
Pressure Ratio;r_p = 12
Inlet temperature of compressor;T1 = 300 K
Inlet temperature of turbine;T3 = 1000 K
cp = 1.005 kJ/kg·K
k = 1.4
Net power output; W' = 70 MW = 70000 KW
A) Now, the formula for the mass flow rate using the total power output of the compressor and turbine is given as;
m' = W'/[cp(T3(1 - r_p^(-(k - 1)/k)) - T1(r_p^((k - 1)/k))
At, 100% efficiency, plugging in the relevant values, we have;
m' = 70000/(1.005(1000(1 - 12^(-(1.4 - 1)/1.4)) - 300(12^((1.4 - 1)/1.4)))
m' = 70000/199.1508
m' = 351.49 kg/s
B) At 85% efficiency, the formula will now be;
m' = W'/[cp(ηT3(1 - r_p^(-(k - 1)/k)) - (T1/η) (r_p^((k - 1)/k))
Where η is efficiency = 0.85
Thus;
m' = 70000/(1.005(0.85*1000(1 - 12^(-(1.4 - 1)/1.4)) - (300/0.85)(12^((1.4 - 1)/1.4)))
m' = 70000/(1.005*(432.09129 - 364.9189)
m'= 1036.91 kg/s
Explanation:
Conduction:
Heat transfer in the conduction occurs due to movement of molecule or we can say that due to movement of electrons in the two end of same the body. Generally, phenomenon of conduction happens in the case of solid . In conduction heat transfer takes places due to direct contact of two bodies.
Convection:
In convection heat transfer of fluid takes place due to density difference .In simple words we can say that heat transfer occur due to motion of fluid.
In the case above, the sum of forces on node 2 (upper-left) is said to be zero.
<h3>What is net
force?</h3>
If any object is said to be falling at constant speed. The net force is often known to be zero.
in the case above, you see that 2 and 3 node is falling down therefore, node 1 and 4 will be zero.
So, In the case above, the sum of forces on node 2 (upper-left) is said to be zero.
