7. Aflat thin plate is dragged at a constant velocity of 4 m/s on the top of a 5 mm deep liquid layer of viscosity 20 centipoise. If the area of the plate is 1 m² find the drag force. Assume variation of velocity in the liquid to be linear. [Ans. 16 N]

A flat-bottomed raft is traveling across a shallow lake at 6 ms-¹. The lake is 10 cm deep. If the raft has a surface area of 3 m² and the lake is full of water with viscosity of 0.001 Pa s, determine the force required to maintain the raft's speed. [0.18 N]

Question 1 pls. Complete solution and correct units. Thanks

Please solve in simplest terms

Can anyone answer this with solution? Thank you

I already calculated the viscosity to be 1.91  but I don't know how to derive the propagation error calculation of viscosity.  help
