2 PARTs (A &B)- SOLVE CAREFULLY!! Please Write Clearly and Box the final Answer(s) ( Use images Below - Pay attention to numbers given)
The diagram depicts a simplified representation of a four-stroke combustion engine cycle, typically found in internal combustion engines.

1. **Intake Stroke (Labeled "1")**: 
   - The intake stroke begins when the piston moves down the cylinder's bore from top dead center (TDC) to bottom dead center (BDC). 
   - This movement creates a vacuum that allows the air-fuel mixture to enter the cylinder through the intake valve.

2. **Compression Stroke (Labeled "2")**: 
   - During the compression stroke, the piston moves back up the bore from BDC to TDC.
   - The air-fuel mixture is compressed in the cylinder, increasing its temperature and pressure.

3. **Power Stroke (Labeled "3")**: 
   - The power stroke starts with the ignition of the compressed air-fuel mixture by a spark plug (in gasoline engines) or by the heat of compression (in diesel engines).
   - The combustion generates a significant explosion and force, pushing the piston down from TDC to BDC.

4. **Exhaust Stroke (Labeled "4")**: 
   - During the exhaust stroke, the piston moves back up the cylinder from BDC to TDC.
   - This movement expels the burnt gases from the combustion chamber through the exhaust valve, allowing the cycle to begin anew with the intake stroke.

The engine cycle is a continuous process, repeated consistently to convert fuel into mechanical energy, powering the vehicle.

Consider a simple network of blood vessels shown in the figure. Segment 1 has a diameter of 1 cm, whereas segments 2, 3, and 4 have a diameter of 0.25 cm. All the segments have a length of 10 cm.

(a) If the total pressure drop Δp between the inlet and outlet is 100 mmHg, compute the blood flow rates in each segment, assuming representative values for whole blood viscosity and density.

(b) If the diameter of segment 2 is reduced to 0.22 cm, compute the new flow rates through each of the segments.

(Assume blood viscosity μ = 3.5 cP and density 1.060 g/cm³ and laminar flow.)
