Answer:
P=- 88.41 KW
Negative sign indicates that power is given to the system.
Explanation:
Given that
P₂=500 KPa
T₂=130°C
V₂=100 m/s
mass flow rate ,m= 0.8 kg/s
Lets take inlet condition for air
T₁=25°C
P₁=100 KPa
V₁=0 m/s
We know that
Heat capacity for air Cp=1.005 KJ/kg.k
We know that for air change in enthalpy only depends only on temperature
Now from first law for open system
W=-110.52 KJ/kg
Shaft power P = m .W
P = -110.52 x 0.8
P=- 88.41 KW
Negative sign indicates that power is given to the system.
Answer:
answer is given below
Explanation:
Declaration for garnet
- void garnet(char,int (*f)(int));
- void - garnet return nothing
garnet accepts two parameters
- 'Char'
- function
Function as a parameter
and here
first int refers return type of function
- (*f) function as pointer variable
second int
- arguments that accept by inner function- function as a parameter
so here Garnet is a function that accepts two parameters. One parameter that contains the character and another parameter that takes an argument (here I am taking an integer) and returns an integer. Function The function returns nothing. Zero is mentioned here.
Answer:
Explanation:
The pump is modelled after applying Principle of Energy Conservation, whose form is:
The head associated with the pump is cleared:
Inlet and outlet velocities are found:
Now, the head associated with the pump is finally computed:
The power that pump adds to the fluid is:
Native Americans who used spears to hunt were using wedges. In the third century BC, the Greek scientist Archimedes invented a way to lift water, called the Archimedes screw. It was used to water crops and to move water out of ships.
