Answer:
Flow rate 2.34 m3/s
Diameter 0.754 m
Explanation:
Assuming steady flow, the volume flow rate along the pipe will always be constant, and equals to the product of flow speed and cross-section area.
The area at the well head is
So the volume flow rate along the pipe is
We can use the similar logic to find the cross-section area at the refinery
The radius of the pipe at the refinery is:
So the diameter is twice the radius = 0.38*2 = 0.754m
Answer:
d) Agility
Explanation:
Agility is defined as the capability or ability of the body to change the position of the body efficiently, and it requires the isolated movement's integration skills by using a combination of speed, balance, reflexes, coordination, strength, and endurance.
In the field of sport, it is categorized in a unique sport because it is a combination of various factors.
Therefore, agility is a component that is related to skill-related physical fitness.
Answer:
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
