Answer:
40.7 m
Explanation:
Let point 1 represent the surface of the water, point 2 be the top of the water trajectory and the reference be the bottom of the tank. Hence:
Answer:
Well, you ALWAYS want to plan ahead, how much gas money you'll need, to know the hotel you'll stay at (if so.) You also want to eat light and stay hydrated! I think the most important thing to prepare for a long distance trip is, to be comfortable! (:
Explanation:
Answer:
the minimum power input required for this air-conditioning system is 1.20 hp
Explanation:
Given the data in the question;
Temperature inside ( Sink ) T = 70°F = ( 70 + 460 )R = 530 R
temperature outside ( source )T = 100°F = ( 100 + 460 )R = 560 R
= 800 Btu/min
= 100 Btu/min
Now, from the equation of coefficient of performance of refrigerator;
= Desired output / Required input
= / --------- let this be equation 1
= ( ) /
where is the rate heat gained through the wall
is the heat generation from people and lights and appliances.
Now, lets consider the equation coefficient of performance of refrigerator in terms of temperatures;
= / ( - )
we substitute
= 530 / ( 560 - 530 )
= 530 / 30
= 17.667
so we substitute into equation 1;
= / ---------
= ( ) /
17.667 = ( 100 + 800 ) /
17.667 = 900 /
= 900 / 17.667
= 50.94 Btu/min
= ( 50.94 / 42.53 ) hp
= 1.198 hp ≈ 1.20 hp
Therefore, the minimum power input required for this air-conditioning system is 1.20 hp
Answer:
The answer is " and 157.5 MPa".
Explanation:
In point A:
The strength of its products with both the grain dimension is linked to this problem. This formula also for grain diameter of 310 MPA is represented as its low yield point
Here y is MPa is low yield point, x is mm grain size, and k becomes proportionality constant.
Replacing the equation for each condition:
People can get yo = 275 MPa with both equations and k= 15.5 Mpa .
To substitute the answer,
In point b:
The equation is
equation is:
by putting the above value in the formula we get the value that is= 157.5 MPa
