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
applying bernouli eq at two point in pipeline
P1 = P2
v1 = v2
z1 = z2 so we have
POwer 
Power P = 1152.99 hp 0
power needed for each mile 
For each revolution, the satellite covers the circumference
of its orbit.
The circumference of a circle is (pi) x (diameter).
Since the satellite is 22,500 miles from the center, that number
is the radius of the circle. The diameter is 45,000 miles.
The circumference is (pi) x (45,000 miles) = 141,372 miles
The satellite's average speed is 141,372 miles per day, or
(141,372 / 24) = 5,890 miles per hour
relative to the center of the Earth.
Kinetic energy is the energy of the motion.
This is because the kinetic energy can be calculated by using the formula,
K.E.=1/2 mv^2
where, v is the velocity of moving body i.e. the body is in motion.
Answer:
The equation of displacement is 
.
Explanation:
Given that,
Distance = 2.50 m
We need to calculate the equation of wave
Using general equation of wave
....(I)
Where, A = amplitude
t = time
x = displacement
= phase difference
Put the value in the equation
At t = 0, x = 0, y =A
From equation (I)
Hence, The equation of displacement is .
Answer:
D
Explanation:
F = G m1 m2 / r^2 now double r
F = G m1m1/ (2r)^2
F = 1/4 G m1m2/r^2 <===== this is 1/4 of the original
