Answer:

½mv²= KE  

½(1000)?²= 50000

<u>500</u>*?²= <u>50000 </u>

500           500

? ²=100

Square root  

?= 10

10 m/s is you answer

Kinetic Energy = 1/2×m×v²
50000 = 1/2×1000×v²
v = √100
v = 10 m/s

A garden hose attached with a nozzle is used to fill a 10‐ gal bucket. The inner diameter of the hose is 2 cm, and it reduces to
nadya68 [22]

Answer:

Explanation:

Given

Volume of bucket V=10\ gallon

Time taken to fill the bucket t=50\ s

so volume flow rate is \dot{V}=\frac{10}{50}=0.2\ gal/s

1 gal is equivalent to 0.133\ ft^3

\dot{V}=0.0267\ ft^3/s

mass flow rate \dot{m}=\rho \times \dot{V}

\dot{m}=62.4\times 0.0267

\dot{m}=1.668\ lbs

(b)Average velocity through nozzle exit

\dot{V}=Av_{avg}

v_{avg}=\dfrac{0.0267}{\frac{\pi}{4}\times (0.0262)^2}

v_{avg}=49.51\ ft/s
