A: Inexhaustible resources are limited
is true
Solution :
Given data :
p = 315612 Pa
At exit of B,
p =
At exit of A,
We need to determine X component of force () to hold in its place.
From figure,
Substitute all the values,
Therefore, the force required to hold the nozzle in its place along horizontal direction.
Answer:
Explanation:
Your car's owner's manual will provide a maintenance schedule designed to keep your brakes in good condition. Following it is the easiest way to avoid expense repairs and the potential for catastrophic brake failure. But at the very least, you should have your brakes inspected every year.
Answer: The exit temperature of the gas in deg C is .
Explanation:
The given data is as follows.
= 1000 J/kg K, R = 500 J/kg K = 0.5 kJ/kg K (as 1 kJ = 1000 J)
= 100 kPa,
We know that for an ideal gas the mass flow rate will be calculated as follows.
or, m =
=
= 10 kg/s
Now, according to the steady flow energy equation:
= 5 K
= 5 K + 300 K
= 305 K
= (305 K - 273 K)
=
Therefore, we can conclude that the exit temperature of the gas in deg C is .
