A pump and its horizontal intake pipe are located 82 m beneath the surface of a large reservoir. the speed of the water in the i

ntake pipe causes the pressure there to decrease, in accord with bernoulli's principle. assuming nonviscous flow, what is the maximum speed with which water can flow through the intake pipe? (assume atmospheric pressure is 1.01 105 pa.)

<span>Ans : Bernoulli's principle states for incompressible non-viscous flow that p/Ď + gâ™h + (1/2)â™v² = constant Evaluate the equation along a stream line from liquid surface of the reservoir (1) to the inlet of the pipe pâ‚/Ď + gâ™hâ‚ + (1/2)â™v₲ = pâ‚‚/Ď + gâ™hâ‚‚ + (1/2)â™v₂² => vâ‚‚ = âš[ 2â™(pâ‚-pâ‚‚)/Ď + 2â™gâ™(hâ‚-hâ‚‚) + v₲ ] lets make some assumptions: - the pressure at the liquid surface is equal to the atmospheric pressure pâ‚ = 1atm = 101325Pa - the velocity of the liquid at the surface (that is the speed at which the liquid level in reservoir decreases) is quite small, so it may be ignored: v₠≠0 So vâ‚‚ = âš[ 2â™(pâ‚-pâ‚‚)/Ď + 2â™gâ™(hâ‚-hâ‚‚) ] The height difference is fixed. So the only variable remaining is the pressure in the pipe. As higher it is as lower the velocity in the pipe is. So you get the maximum velocity for the minimum pressure. Since pressure cannot drop below zero this is pâ‚‚ = 0 Therefore vâ‚‚max = âš[ pâ‚/Ď + gâ™(hâ‚-hâ‚‚) ] = âš[ 2â™101325Pa/1000kg/mÂł + 2â™9.81m/s²â™12m ] = 20.93m/s</span>

A 50-cm wire placed in an east-west direction is moved horizontally to the north with a speed of 2.0 m/s. the horizontal compone
Strike441 [17]

When a wire is moved inside uniform magnetic field then its free electrons will experience magnetic force on it due to which wire will have potential difference at its ends.

Now here we will have magnetic field due to earth and wire is moving in this constant field so induced emf is given by formula

EMF = v.(B x L)

given that

B = 25\mu Tj - 50\mu Tk

v = 2 m/s j

L = 0.50 m (-i)

now by using the above formula we will have

EMF = 2(j) .(25\mu j - 50\mu k) x (-0.50 i)

EMF = 2(j) .(12.5\mu k + 25\mu j)

EMF = 50 \mu Volts

6. What are 3 different evidences of evolution? How is each form used to provide evidence of evolution?
Cloud [144]

Answer:

Divergent - This type of evolution often occurs when closely related species diversify to new habitats. On a large scale, divergent evolution is responsible for the creation of the current diversity of life on earth from the first living cells. On a smaller scale, it is responsible for the evolution of humans and apes from a common primate ancestor.

Convergent - Convergent evolution causes difficulties in fields of study such as comparative anatomy. Convergent evolution takes place when species of different ancestry begin to share analogous traits because of a shared environment or other selection pressure. For example, whales and fish have some similar characteristics since both had to evolve methods of moving through the same medium: water.

Parallel evolution - Parallel evolution occurs when two species evolve independently of each other, maintaining the same level of similarity. Parallel evolution usually occurs between unrelated species that do not occupy the same or similar niches in a given habitat.

If a graduated cylinder has a current water level of 30 ml and you add an object which causes the water level to rise to 53 ml,
Katen [24]

Answer:

23L

Explanation:

Given that:

Initial volume of water = 30mL

Final volume of water after an object was placed on it = 53mL

The volume object added which resulted in a rise to 5mL will be :

Final Volume of object - Initial volume of object

53 mL - 30mL = 23mL

Hence, volume of object added is 23 mL
