Water flows through a water hose at a rate of Q1 = 860 cm3/s, the diameter of the hose is d1 = 1.85 cm. A nozzle is attached to the water hose. The water leaves the nozzle at a velocity of v2 = 10.8 m/s?

a. Enter an expression for the cross-sectional area of the hose, A1, in terms of its diameter, d1. b. Calculate the numerical value of A1, in square centimeters. c. Enter an expression for the speed of the water in the hose, v1, in terms of the volume flow rate Q1 and cross-sectional area A1. d. Calculate the speed of the water in the hose, v1 in meters per second. e. Enter an expression for the cross-sectional area of the nozzle, A2, in terms of v1, v2 and A1. f. Calculate the cross-sectional area of the nozzle, A2 in square centimeters.

a.) A1 = π (d1/2)^2

b.) A1 = π(1.85cm/2)^2 = 2.688cm^2

c.) Q1 = A1*v1

d.) v1 = Q1 / A1 = 860 cm^3/s / 2.688cm^2 = 319.94 cm/s = 0.31994 m/s

e.) A2 = (A1 * v1)/v2

f.) A2 = (2.688cm^2 * 0.31994 m/s)/10.8m/s = 0.07963 cm^2

What is muzzle velocity?

Muzzle velocity refers to the speed at which a projectile leaves the barrel of a firearm or weapon when fired. It is measured in feet per second or meters per second and plays a significant role in determining the effectiveness and range of a weapon.


How is muzzle velocity measured?

Muzzle velocity is typically measured using a chronograph, which is a device that calculates the speed of a projectile as it leaves the muzzle of a firearm. The chronograph works by measuring the time it takes for the projectile to pass through two sensors a known distance apart, allowing for the calculation of the velocity.


What is the Difference between muzzle velocity and recoil velocity?

Muzzle velocity is the velocity of a bullet as it leaves the firearm's barrel, while recoil velocity is the backward momentum that the firearm experiences when the bullet is fired. Muzzle velocity determines the bullet's speed and trajectory, while recoil velocity affects the shooter's ability to control the firearm during and after firing.


Why does the horizontal velocity of a ball remain the same after it leaves your hand?

The horizontal velocity of a ball remains the same after it leaves your hand because there are no horizontal forces acting on it to change its speed. According to Newton's first law of motion, an object in motion will remain in motion with constant velocity unless acted upon by an external force.


What is the difference between the velocity and muzzle velocity?

well velocity is much stronger than muscle velocity because air velocity is when wind speed catches up with the heaver object and slows it down and muscle velocity is how much weight you can carry there is your answer hope you understand your welcome - Jamie

A rocket ship leaves earth's atmosphere its initial velocity is less than its final velocity which is this an example of?

This is an example of acceleration. Acceleration is the rate at which an object changes its velocity, either by speeding up or slowing down. In this case, the rocket ship is speeding up as it leaves Earth's atmosphere, with its final velocity being greater than its initial velocity.
