Homework Statement
I have attached a jpeg of the question invloved. Involving finding shap factors for both the T and the sqaure piece.
Homework Equations
Due to illness i missed the lecture for this topic and as such i am missing the relevant equations on how to attempt this. If...
I take it that only a percentage of the energy consumed is given off as heat the rest is transferred into other energy forms obeying the energy cannot be creasted or destroyed rule just transformed from one source to another.
How do i work out the pressure knowing that 98 mm is the deflection? I take it i then use this value of pressure in bernoullis equation to work out the velocity .Then for b rearrange this equation for the finding of the deflection with the value of 40 for the velocity.?
thanks
I understand now about the manometer gives an indication as to the pressure in the test section.
Are any of my initial theries correct or do i need to rethink them? I take it there's a pressure drop and the speed increasees in the test area creating the deflection h. How do i go about working...
static pressure+ dynamic pressure = total pressure
Ps+ (densityx V2/2)= total pressure so therefore as the speed increases the total pressure increases, How does this apply to a deflection in a manometer?
I thought that myself about the question a little misleading, so volume is proportional to temperature at a constant pressure meaning that if heat is added the volume will increase and the pressure remains constant. Cheers for the quick reply you don't by any chance have any ideas about the...
Homework Statement
If heat is transferred to air inside a cylinder and the volume doubles does the pressure change ?
[b]2. Homework Equations + thoughts about the statement
My thoughts are that energy is given to the air molecules inside the cylinder causing the volume of the air to...
1. Homework Statement
Air at 20 degrees celsius and 100kpa is drawn into a wind tunnel. If the deflection h of a water manometer that is connected to a hole in the wall of the test section to measure the gauge pressure in the flow is 98mm. Calculate air speed in test section in m/s ignore...
