Question 5 A pipe has a radius of 10 cm, and the fluid flowing through this pipe is 15 m/s. The pipe bends downwards and falls 5 m. Given the density of the fluid in this pipe is 800 kg/m³, calculate the difference in pressure between the beginning and end of this pipe. Question 6 A boat whose mass is 5000 kg is floating on the surface of the water where 1/4 of its volume is submerged below the surface. Given the density of seawater to be 1100 kg/m3, what must be the density of the boat?
