Challenge Problems
Push your limits with challenges.
Question 1
A fluid has a bulk modulus of 2500 kPa. If the pressure is increased by 500 kPa, what is the expected change in volume for a fluid with an initial volume of 1 m3?
💡 Hint: Rearranging the formula will help find the change in volume.
Question 2
Given a surface tension of 0.072 N/m for water, calculate the pressure difference inside a bubble of radius 1 mm. Is the pressure inside higher or lower?
💡 Hint: Recall the formula for pressure difference due to surface tension.
