Question

An irrigation system has a 2.5 cm diameter hose, which shoots
water at 60 ° from the horizontal, at 5.5 m / s, and is placed on
the ground. If we think that each droplet moves like a projectile,
calculate:

a- the maximum height that each droplet rises

b- the time it takes to reach its maximum height

c- the horizontal reach of the jet measured from the hose
pistil

Answer #1

Juanito throws water with a hose, pointing it 35 ° upwards from the horizontal.
Sale of water at 17 m / s by the pistil. Let's assume that each drop behaves as if it were a
simple project and that the pistil is at ground level. Calculate
a- the time it takes for each drop to rise to the maximum height
b- how far to reach the water jet, measured horizontally from the pistil?
c- the height that the jet...

A 2.54 cm inner diameter hose is connected to a
freshwater pump with a gauge pressure of 3.65 atm. The volume flow
rate at the pump is 2.50 gal/min. The other end of the hose is held
at an angle of 300 above the horizontal at a height of
1.20 m.
Determine the velocity of the water as it exits the hose.
Determine the inner diameter of the hose as the water exits the
hose.
Determine the horizontal distance from...

1) Water leaves a fireman’s hose (held near the ground) with an
initial velocity v0 = 21.5 m/s at an angle
θ = 29° above horizontal. Assume the water acts as a
projectile that moves without air resistance. Use a Cartesian
coordinate system with the origin at the hose nozzle position.
Part (a) Using v0,
θ, and g, write an expression for the time,
tmax, the water travels to reach its maximum
vertical height.
Part (b) At what horizontal distance...

A toy gun shoots spherical plastic projectiles by means of a
spring. A typical projectile has a mass of m = 25 g. The spring
used has a spring constant of k = 18.6 N/m, and when put under
load, it is displaced 10 cm, as shown in Figure P6.92. The barrel
of the gun exerts a slight frictional force, Ffriction=
-0.1512 N, on the pellet as it moves down the barrel from its
starting point over a total length...
