Problem 45 Medium Difficulty

A shower head has 20 circular openings, each with radius 1.0 $\mathrm{mm} .$ The shower head is connected to a pipe with radius 0.80 $\mathrm{cm} .$ If the speed of water in the pipe is $3.0 \mathrm{m} / \mathrm{s},$ what is its speed as it exits the shower-head openings?

Okay, So in this problem, we just need to apply the equation of continue with you, which say's that the initial speed ups issue bfv switch here. The initial speed times, the initial or sectional area. It's going to be equal the final, its speed times, the final cross sectional area. In this case, we have area that is circular. So let's see, we have that are area is going to be, uh, by times their radios square. Okay, so know that we have the equation of continuity. We can answer the problem. So if we want to calculate the exit speed so the final speed, we can say that the final speed is going to be cool. The initial speeds times the initial cross sectional area divided by the Final Course sectional area. But who is a I in F? So let's put in here. We know that the initial area is going to be let's see, all right, times 0.8, which is the first to Raiders Square in the final area. It's going to be ah, 20 by they're multiplies 0.1, it's square. We have to move supply by 20 because the shower the shower had has 20 circular openings, so we're not considered a one opening way. Are considering all the 20 openings. Therefore, we need to put 20. And here Okay, so now that we have all the information, we can finally calculate the exit speed. So decks it's It's going to be three on multiplies by zero point eight square, divided by 20 by they're multiply 0.1 square. Okay, so we can cross by in here and finishing the calculation we get there or finer speech. VF. That's it's a better V in here. The final speed. It's going to be Quote nine 0.6 meters first seconds, and that's the final answer. Thanks for watching.
