be 0.20 . If, instead, a 0.40 mass were used in this same experiment, choose the correct value for the maximum speed.
a. 0.40 m/s.
b. 0.20 m/s.
c. 0.28 m/s.
d. 0.14 m/s.

Answer:

d

Explanation:

Ya gon find the Kenitic Energy first

K=½mv²===> K=½×0.2×(0.2)²===> 0.1(0.04)===> 0.004

and now the replacement:

0.004=½×0.4V²====> v²=0.02===> V=0.14m/s

You work for the city water department and need to pump 3400 liters/minute of water from a tank at ground level into a vented (i
umka21 [38]

Answer:

P_E=46.2778\ kW

v=1.804\ m.s^{-1}

Explanation:

Given:

  • flow rate of water, \dot{V}=3400\ L.min^{-1}=3.4\ m^3.min^{-1}

<em>∵Density of water is 1 kg per liter</em>

∴mass flow rate of water, \dot{m}=3400\ kg.min^{-1}

  • height of pumping, h=75\ m
  • efficiency of motor drive, \eta=0.9
  • diameter of pipe, D =0.2\ m

<u>Now the power required for pumping the water at given conditions:</u>

P=\dot{m}.g.h

P=\frac{3400}{60} \times 9.8\times 75

P=41650\ W

<u>Hence the electric power required:</u>

P_E \times \eta=P

P_E \times 0.9=41650

P_E=46.2778\ kW

<u>Flow velocity is given as:</u>

v=\dot{V}\div a

where: a = cross sectional area of flow through the pipe

v=\frac{3.4}{60}\div (\pi.\frac{0.2^2}{4} )

v=1.804\ m.s^{-1}

How much extra water does a 147-lb concrete canoe displace compared to an ultralightweight 38-lb kevlar canoe of the same size c
romanna [79]

We use the formula, to calculate the volume of water displaced by concrete canoe,

V =\frac{W}{\gamma }

Here, W is the weight of concrete canoe and \gamma is the specific weight of water and its value is 62.4\ lb/ft^3.

So,

V =\frac{ 147\ lb}{62.4\ lb/ft^3}=2.356\ ft^3.

Now the volume of water occupied in ultra lightweight kevlar canoe,

v=\frac{w}{\gamma}

Here, w is weight of  kevlar canoe.

So,

v=\frac{38\ lb}{62.4\ lb/ft^3} =0.6089\ ft^3

Thus, the volume of water displaced,

=V-v=2.356\ ft^3-0.6089\ ft^3=2.19\ ft^3.

Hence, the volume of water displaced canoe compared to an ultra-lightweight  kevlar canoe is 2.19\ ft^3
