Answer:
HP = 27.08 hp
Explanation:
The complete question has a theoretical flow rate of 18.2 GPM. So, to find the input horsepower, we will use the following formula:
HP = QP/1714(E)
where,
HP = Input Horse Power = ?
Q = Volume Flow Rate in Gallons Per Minute (GPM) = 18.2 GPM
P = Outlet Pressure in psi = 2372 psi
E = Mechanical Efficiency = 0.93
Therefore,
HP = (18.2 GPM)(2372 psi)/(1714)(0.93)
<u>HP = 27.08 hp</u>
The answer is; C
In particular points in the earth’s surface, underground water is naturally heated to steam that can be harness for geothermal energy. The steam that ejects from the ground with high kinetic energy can be used to turn turbines that generate electricity. The underground water is usually heated by the hot rocks beneath that are subjected to the immense heat of magma or the enormous pressure of overlying crust.
Answer:
the knee extensors must exert 15.87 N
Explanation:
Given the data in the question;
mass m = 4.5 kg
radius of gyration k = 23 cm = 0.23 m
angle ∅ = 30°
∝ = 1 rad/s²
distance of 3 cm from the axis of rotation at the knee r = 3 cm = 0.03 m
using the expression;
ζ = I∝
ζ = mk²∝
we substitute
ζ = 4.5 × (0.23)² × 1
ζ = 0.23805 N-m
so
from; ζ = rFsin∅
F = ζ / rsin∅
we substitute
F = 0.23805 / (0.03 × sin( 30 ° )
F = 0.23805 / (0.03 × 0.5)
F F = 0.23805 / 0.015
F = 15.87 N
Therefore, the knee extensors must exert 15.87 N
Answer:
The magnitude of a uniform electric field that will stop these protons in a distance of 2 m is 1.01 x
N/C
Explanation:
given information,
kinetic energy, KE = 3.25 x
J
proton's mass, m = 1.673 x
kg
charge, q = 1.602 x
C
distance, d = 2 m
to find the electric field that will stop the proton, we can use the following equation:
E = F/q
= (KE/d) / q , KE = Fd --> F = KE/d
= KE/qd
= (3.25 x
J) / (1.602 x
C)(2 m)
= 1.01 x
