Question

(a) What is the pressure drop (in N/m2) due to the Bernoulli effect as water goes into a 3.50 cm diameter nozzle from a 9.10 cm diameter fire hose while carrying a flow of 34.0 L/s?

Answer is in unit N/m2

(b) To what maximum height (in m) above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.)

Answer is in unit m

What is the change in speed (in m/s) due to the Bernoulli effect
as water goes into a 3.19 cm-diameter nozzle from a 9.26
cm-diameter fire hose while carrying a flow of 40.9 L/s?

as water goes into a 2.72 cm-diameter nozzle from a 8.69
cm-diameter fire hose while carrying a flow of 40.4 L/s?

A sump pump (used to drain water from the basement of houses
built below the water table) is draining a flooded basement at the
rate of 0.600 L/s, with an output pressure of 3.50 ✕ 105
N/m2. You may neglect frictional losses in both parts of
this problem.
(a) The water enters a hose with a 3.00 cm inside diameter and
rises 3.00 m above the pump. What is its pressure (in
N/m2) at this point?
_________ N/m2
(b) The...

Water flows at 3.9 m / s through a garden hose of a diameter of
2.10 cm and emerges from a nozzle of a radius of 0.56 cm. If the
nozzle is directed vertically upward, to what height would the
water rise? Give your answer to two decimal places and remember add
unit m after the numerical value.

A sump pump (used to drain water from the basement of houses
built below the water table) is draining a flooded basement at the
rate of 0.610 L/s, with an output pressure of 2.80×105
N/m2. The water enters a hose with a 2.90–cm inside
diameter and rises 2.70 m above the pump. What is its pressure at
this point?
3.06*10^5 N/m^2

In a water pistol, a piston drives water through a larger tube
of area A1 into a smaller tube of area
A2 as shown in the figure below. The radius of
the large tube is 1.20 cm and that of the small tube is 1.50 mm.
The smaller tube is 3.00 cm above the larger tube.
