Jake was playing making a paper airplane, after making he kept it on the table and went to have food.
Suddenly his brother saw the plane and threw it in the air, The airplane kept flying for about 3m/s and it hit his mother and due to the force the plane stopped.
{kept in on the table>rest
brother threw the plane>moving
it hit his mother>force that stopped it}
(mark me brainliest if you're satisfied with my answer)
Answer:
The value of gauge pressure at outlet = -38557.224 pascal
Explanation:
Apply Bernoulli' s Equation
+
+
=
+
+
--------------(1)
Where
= Gauge pressure at inlet = 3.70105 pascal
= velocity at inlet = 2.4
= Gauge pressure at outlet = we have to calculate
= velocity at outlet = 3.5
= 3.6 m
Put all the values in equation (1) we get,
⇒ +
=
+
+ 3.6
⇒ 0.294 = + 0.6244 + 3.6
⇒ = 0.294 - 0.6244 - 3.6
⇒ = - 3.9304
⇒ = - 38557.224 pascal
This is the value of gauge pressure at outlet.
Substitute your values into the formula:
W = Work done = 288
= 360
Solve to find e:
e = 288 ÷ 360 = 0.8
Convert e to a percentage by multiplying by 100.
0.8 × 100 = 80
<h2>D. 80%</h2>
