Question

Question 1 A nozzle with a diameter of 0.4 cm is attached to a garden hose with a radius of 10 cm. The flow rate through hose and nozzle is 0.500 L/s. 1) Calculate the speed of the water in the hose. 2) Calculate the speed of the water in the nozzle. 3) Calculate the pressure in the hose, given that the absolute pressure in the nozzle is $1.01 \times 10^5$ N/m$^2$ (atmospheric, as it must be) and assuming level, frictionless flow.

Step 1

To calculate the speed of the water in the hose, we can use the equation for flow rate: Q = A * v where Q is the flow rate, A is the cross-sectional area of the hose, and v is the velocity of the water. The cross-sectional area of the hose can be calculated Show more…

A nozzle with a diameter of 0.4 cm is attached to a garden hose with a radius of 10 cm. The flow rate through the hose and nozzle is 0.500 L/s. 1. Calculate the speed of the water in the hose. 2. Calculate the speed of the water in the nozzle. 3. Calculate the pressure in the hose, given that the absolute pressure in the nozzle is 1.01 x 10^5 N/m^2 (atmospheric, as it must be) and assuming level, frictionless flow.
