A Newtonian fluid fills the clearance between a shaft and a sleeve. When a force of 0.9 kN is applied to the shaft parallel to the sleeve, the shaft attains a speed of 1.25 cm/s. What will be the speed of the shaft if a force of 3 kN is applied?

Can you answer number 3  please

The tank shown has one curved surface restraining a body of static fluid, with the following dimensions: w = 5.25 m h1 = 2.4 m R1 = 0.90 m Required Compute the magnitude of the resultant force, in kN, to the nearest 100th. Water h1 R1

2-liter soda bottles do not have flat bottoms. A bottle can be approximated as a cylinder filled from the bottom up to 0.26-m high with a hemispherical space of 10-cm-diameter underneath. If you treat the soda as having the density of water, what is the force in N of the soda on the curved bottom of the soda bottle?
