Which is the best description of power? A. the amount of kinetic energy lost during motion
cestrela7 [59]

Answer:

D. a measure of how fast a machine performs work​

Explanation:

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

Power = \frac {Energy}{time}

Hence, the best description of power is that, it is a measure of how fast a machine performs work.

This can be calculated by using the mathematical expression below;

Power = \frac {Work done}{Time}

But we know that, Workdone = force * distance

Oil with a kinematic viscosity of 4 10 6 m2 /s fl ows through a smooth pipe 12 cm in diameter at 2.3 m/s. What velocity should w
Setler79 [48]

Answer:

Velocity of 5 cm diameter pipe is 1.38 m/s

Explanation:

Use following equation of Relation between the Reynolds numbers of both pipes

Re_{5} = Re_{12}

\sqrt{\frac{V_{5}XD_{5}  }{v_{5}}}= \sqrt{\frac{V_{12}XD_{12}  }{v_{12}}}

Re_{5} = Reynold number of water pipe

Re_{12} = Reynold number of oil pipe

V_{5} = Velocity of water 5 diameter pipe = ?

V_{12} = Velocity of oil 12 diameter pipe = 2.30

v_{5} = Kinetic Viscosity of water = 1 x 10^{-6} m^{2}/s

v_{12} = Kinetic Viscosity of oil =  4 x 10^{-6} m^{2}/s

D_{5} = Diameter of pipe used for water = 0.05 m

D_{12} = Diameter of pipe used for oil = 0.12 m

Use the formula

\sqrt{\frac{V_{5}XD_{5}  }{v_{5}}}= \sqrt{\frac{V_{12}XD_{12}  }{v_{12}}}

By Removing square rots on both sides

{\frac{V_{5}XD_{5}  }{v_{5}}}= {\frac{V_{12}XD_{12}  }{v_{12}}}

{V_{5}= {\frac{V_{12}XD_{12}  }{v_{12}XD_{5}\\}}xv_{5}

{V_{5}= [ (0.23 x 0.12m ) / (4 x 10^{-6} m^{2}/s) x 0.05 ] 1 x 10^{-6} m^{2}/s

{V_{5} = 1.38 m/s
