5 0

Answer:

0.5A

Explanation:

V=IR where V is 1.5V, R is 3 ohms

Hence 1. 5= I x 3

1.5/3 =I

I =0.5 A

Current is 0. 5 amperes

A Keystone Pipeline has a diameter of 36 inches and a design flow rate of 590,000 barrels per day of crude oil at 40ºC. Estimate

Sav [38]

Answer:

Power = 606.83 hp/mile

Explanation:

Given data:

diameter of pipeline is 36 inches = 3ft

flow rate is 590,000 barrels per day = 28.755 ft^3/sec

temperature of pipe = 46 degree celcius

length of pipe is 1.9 mile = 10032 ft

velocity of flow $= \frac{28.755}{\frac{\pi}{4} 3^2} = 4.068 ft/s$

applying bernouli eq at two point in pipeline

P1 = P2

v1 = v2

z1 = z2 so we have

$h_{in} = h_f$

$h_{in} = \frac{ flv^2}{2gD}$

$h_{in} = \frac{0.0155 \times 10032 \times 4.068^2}{2\times 32.174 \times 3}$

$h_{in} = 13.32 ft$

POwer $P = \rho gQ h_{in}$

$P = 53.71 \times 32.174 \times 27.755 \times 13.32 = 634141.29 ldf ft/sec$

Power P = 1152.99 hp 0

power needed for each mile $= \frac{1152.99}{1.9} = 606.83 hp/mile$

A person slaps her leg with her hand, which results in her hand coming to rest in a time interval of 2.75 ms from an initial spe

bazaltina [42]

Answer:

1350N

Explanation:

$2.75 ms = 2.75*10^{-3}s$

The force exerted on the hand would be the momentum divided by the duration of contact.

As the hand is coming to rest, final velocity would be 0

$F = \frac{\Delta P}{\Delta t} = \frac{m(0 - v)}{\Delta t} = \frac{1.65*(2.25 - 0)}{2.75 * 10^{-3}} = -1350 N$

The magnitude of the force would be 1350N
