Answer:
1. 80,000 Pa
2. 11.3 m/s
3. 12.5 m/s
Explanation:
<u>Question 1</u>
Pressure,
Where h is the height that water is to reach, g is gravitational constant and is the density, in this case, we assume
of pure water as
Assuming
P=8*10*1000=80000 Pa
<u>Question 2</u>
Pressure can also be found by the formula
where v is the velocity
Equating the new formula of pressure to the formula used in question 1 above
Notice that is common hence
Making V the subject of the formula
In this case, h=8-1.6=6.4m and taking g as 10 m/s^{2}
Rounding off to 1 decimal place
v=11.3 m/s
<u>Question 3</u>
As already illustrated
Taking g as 9.8 and h now is 8m
v=12.52198067
Rounding off to 1 decimal place
v=12.5 m/s
