Answer:
Explanation:
Given that:
Gage pressure at the inlet = 20psig
Inlet diameter D = 4 in
Exit diameter d = 1.5 in
Volumetric flow rate at inlet
= 2ft³?s
Applying continuity and the x component of the momentum;
we have:
Q =
=
Velocity at inlet is calculate as :
= 22.92 ft/s
Velocity at the exit:
= 162.98 ft/s
The required external force can be calculated by using the formula:
Thus, the external force required to hold the orifice in place
Stone exerts force on table and in reaction table exerts force called "Normal Reaction" on stone in upward direction. Due to which it does not fall. Friction also causes stone to be in rest.

You were a freeloader of my questions, so I'll be one too.
Dead space is the name of the air in the conducting zone that is not available for gas exchange.
What is conducting zone?
The conducting zone consists of all of the structures that provide passageways for air to travel into and out of the lungs.
- The conducting zone is part of the respiratory system. It serves as a route for incoming and outgoing air and filtering debris and pathogens from the incoming air.
- In order to compensate for the reduction in gas exchange in the respiratory system, ventilation will increase
The volume of air that is inhaled that does not take part in the gas exchange is dead space. Because it either remains in the conducting airways or reaches alveoli that are not perfused or poorly perfused.
Dead space volume is air in the conducting airways that does not participate in gas exchange between the alveoli and blood.
Hence,
Dead space is the name of the air in the conducting zone that is not available for gas exchange.
