Answer:
the third statement is true
Explanation:
given data
Lenovos cost more than Dells
Lenovos cost less than Apples
solution
we have given 1st statement that is express as
cost (Lenovo) > cost (Dell) ..................1
and
2nd statement that is express as
cost (Lenovo) < cost (Apple)
so we can say it as
cost (Apple) > cost (Lenovo) ......................2
and
now above Both equation 1 and 2 can be written as
cost (Apple) > cost (Lenovo) > cost (Dell) .........................3
so we can say cost of Apples is more than the cost of Lenovos and the cost of Dells
so as that given 3rd statement is true
Answer:
∆x = A / √2
Explanation:
If the mass is oscillating in a SHM, the total mechanical energy at any time is given by the following equation:
½ k A2 = ½ k (∆x)2 + ½ mv2
We are told that at the point that we are looking for, the elestic potential energy, and the kinetic energy, are equal each other.
As we have no information regarding kinetic energy, we can replace it with the equivalent in potential energy, so we have:
½ k (∆x)2 + ½ mv2 = 2 (1/2) k (∆x)2 = k (∆x)2
We know that this energy must be equal to ½ k A2, so we can put the following:
½ k A2 = k (∆x)2
Simplifying common terms, and solving for the displacement from the equilibrium point (∆x), we get:
∆x = A / √2

Answer:
Pump factor = Fp = 7.854 gal/cycle
Ev = 82.00 %
P_H = 183.29 hp
Explanation:
Given data:
Dimension of duplex pump
6.5 inch liner
2.5 inch rod
18 inch strokes
Pressure 3000 psig
Pit dimension
7 ft wide
20 ft long
Ls = 18 inch
Velocity = (18)/10
volumetric efficiency is given as E_v = (Actual flow rate)/(Theortical flow rate) * 100
we know that flow rate is given as = Area * velocity
Theoritical flow rate
Ev = 82.00 %
Pump factor
Fp = 1814.22 in^3/cyl
Fp = 7.854 gal/cycle
Flow rate
Power
