Properties of Fluid

What is the mass of the fluid per unit volume. Its unit measurement is kg/m3?

• Mass

• Density

• Pressure

𝑆𝑝𝑒𝑐𝑖𝑓𝑖𝑐 𝑤𝑒𝑖𝑔ℎ𝑡 (γ) = 𝑤𝑒𝑖𝑔ℎ𝑡 𝑜𝑓 𝑓𝑙𝑢𝑖𝑑 (𝑁)/ 𝑣𝑜𝑙𝑢𝑚𝑒 𝑜𝑓 𝑓𝑙𝑢𝑖𝑑 (m3)

• True

• False

Mass is measured by Kg, while weight is measured by N

• True

• False

Specific volume is equal to the inverse of the Density

• True

• False

𝑆𝑢𝑟𝑓𝑎𝑐𝑒 𝑡𝑒𝑛𝑠𝑖𝑜𝑛 (T) = 𝐹𝑜𝑟𝑐𝑒 (𝑁) * 𝑆𝑢𝑟𝑓𝑎𝑐𝑒 𝑙𝑒𝑛𝑔𝑡ℎ (𝑚)

• False

• True

It is better to place the water tank on the roof of the building because:

• We will not need a pump

• The flow of water will be easier due to the pressure

• The water will be distributed to the houses depending on the gravity force (Weight)
