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 turntable has an angular velocity of 3.5 rad/s. A dust bunny is on the disk of the turntable at a distance of 0.2m from the ce

diamong [38]

Answer:

E. 0.25

Explanation:

Given that

Angular speed ω = 3.5 rad/s

Distance ,r= 0.2 m

Lets take mass of dust bunny = m

We know that

Radial force F = m ω² r

The friction force on the dust bunny Fr

Fr= μ m g

To getting slung off dust bunny from disk

m ω² r = μ m g

ω² r = μ g

3.5² x 0.2 = μ x 10 ( take g =10 m/s²)

μ = 0.245

μ = 0.25

Therefore answer is E

E. 0.25
