Pressure units are used to measure the force exerted on a surface per unit area.

• Pressure is typically measured in units such as pascal (Pa), bar, psi, or atmosphere (atm).

• 1 pascal (Pa) is equal to 1 newton per square meter (N/m²).

• 1 bar is approximately equal to atmospheric pressure at sea level (1 atm).

• 1 psi (pound per square inch) is equal to approximately 6895 pascals (Pa).

The fire triangle is a model that explains the three elements required for a fire to start and continue. Diamonds are a form of carbon that is highly valued for their beauty and durability.

• The fire triangle consists of three elements: fuel, heat, and oxygen.

• If any of these elements are removed, the fire will be extinguished.

• Diamonds are formed deep within the Earth's mantle and are brought to the surface through volcan...read more

The Bernoulli equation relates the pressure, velocity, and elevation of a fluid in a streamline.

• The Bernoulli equation is a fundamental equation in fluid dynamics.

• It states that the total energy of a fluid remains constant along a streamline.

• The equation relates the pressure, velocity, and elevation of the fluid.

• It is derived from the principle of conservation of energy.

• The equation is commonly used in various applicat...read more

Resin is measured in kg/liter by calculating the weight of resin in kilograms and dividing it by the volume in liters.

• Resin weight in kilograms is divided by the volume in liters to get the measurement in kg/liter.

• For example, if you have 5 kg of resin in a container with a volume of 2 liters, the measurement would be 5 kg / 2 liters = 2.5 kg/liter.
