1. What is Blood Density?

Definition: Blood density refers to the mass of blood per unit volume, typically measured in kilograms per cubic meter (kg/m³).

Normal Value: The average density of human blood is approximately 1050 kg/m³ at 37°C.

2. How Does the Calculator Work?

The calculator uses the density formula:

\[ \rho = \frac{m}{V} \]

Where:

\( \rho \) — Density of blood (kg/m³)
\( m \) — Mass of blood (kg)
\( V \) — Volume of blood (m³)

Explanation: The mass of blood is divided by its volume to calculate density.

3. Importance of Blood Density

Details: Blood density affects circulation, diagnostic tests, and medical procedures. It's influenced by factors like hematocrit, plasma proteins, and temperature.

4. Using the Calculator

Tips: Enter the mass of blood in kilograms and volume in cubic meters. For typical human blood (5 liters), mass is about 5.25 kg (5L × 1050 kg/m³).

5. Frequently Asked Questions (FAQ)

Q1: What's the density difference between whole blood and plasma?
A: Plasma density is ~1025 kg/m³, while whole blood is ~1050 kg/m³ due to red blood cells.

Q2: How does temperature affect blood density?
A: Density decreases as temperature increases (thermal expansion).

Q3: What's the clinical significance of blood density?
A: It affects centrifugation, blood separation, and diagnostic equipment calibration.

Q4: How does anemia affect blood density?
A: Anemia typically reduces blood density due to lower hematocrit (fewer red blood cells).

Q5: Can I use liters instead of cubic meters?
A: Yes, but convert liters to m³ first (1 liter = 0.001 m³) for accurate kg/m³ results.
