Answer:

The BHP would be "65.659 HP".

Explanation:

The given values are:

Discharge,

Q = 0.2 m³/s

Dynamic head,

H = 20 m

Efficiency,

% = 80%

Now,

The Power will be:

⇒ P=\delta QH

On substituting the values, we get

⇒     =1000\times 9.81\times 0.2\times 20

⇒     =39240 \ W

The brake horse power will be:

⇒ BHP=\frac{100 Q H}{3960n}

On putting values, we get

⇒           =\frac{100\times 0.2\times 20}{3960\times 0.80}

⇒           =65.659 \ HP

A specimen of commercially pure copper has a strength of 240 MPa. Estimate its average grain diameter using the Hall-Petch equat
romanna [79]

Answer:

3.115× 10^{-3} meter

Explanation:

hall-petch constant for copper is given by

      S_0=25 MPa

      k=0.12 for copper

now according to hall-petch equation

S_Y=S_0 +\frac{K}{\sqrt{D}}

240=25+\frac{0.12}{\sqrt{D}}

D=3.115× 10^{-3} meter

so the grain diameter using the hall-petch equation=3.115×  10^{-3} meter

Nikolay [14]

Answer:

Aluminum

Explanation:

The best material to use when creating an electric fence would be Aluminum. Aluminum wiring is incredibly durable and can be easily obtained. Since aluminum is a non-magnetic metal its conducting capabilities far exceed other metallic options in the market and is also why companies choose aluminum for their high tension cable wiring. Aside from being more expensive than other feasible options its durability and conducting capabilities make it easily the best option.
