Transcript

00:01 We are given here nozzle.

00:03 We are given here a nozzle with a diameter.

00:06 So we are given here a diameter d which is equal we can write 0 .500 cm and is attached to a garden hose with a radius.

00:19 So we are given here radius or which is equal we can write 1 centimeter the radius with 1 centimeter now a nozzle with diameter that is a nozzle with diameter and it of garden hose and the flow rate through the hose and nozzle so we can write the flow rate flow rate that is denod ever q which is equal to we are given here 0 .50 per second and we want to find the speed of the water so we want to find speed of the water so in the first part of this question we want to find speed of the hose so the in hose so you can write how to find speed of the in -hose so we know that the area first finding the area which is equal we can write pi r square which a substitute value so we know the value of pi 314 and we know the radius here said r which is equal to 1 cm we can weigh 0 .0 1 meter so we just substitute that value 0 .01 square and we can write here value of area which is equal to answer is 3 .14 multiplied by 30 minus 4 meter square so this is the value of area a and let's write about here the v which is equal to we want to find the speed speed which is equal to we know that q divided by a which is equal to value of flow rate 0 .5 divided by area 3 .14 by 10 to minus 4 now we just simply find we can write here answer is so here the answer here is and we know that a that liter so we just converted in a meter cube so we can write to 10 to minus 3 which is a equal to answer is 1 .5 .9 .15 meter per second.

02:08 So this is the value of the speed of the hose.

02:11 Now let's find out our second support of this question...

Question

100 m A water diameter = 15cm valve D nozzle diameter = 8 cm B C 30cm 500 m 500 m \nu_{H2O} = 1.007 \times 10^{-6} m^2/s all components are cast iron, pipe entrances are find the volumetric flow rate of the nozzle. sharp edged.
