Two parallel, horizontal plates that are 0.5 m apart and have 40C water between them are initially at rest. Later moves the upper plate with a force such that the upper layer of water reaches a speed of 0.25 m/s. If the viscosity of water at this temperature is 6.53x10-4 kgm-1s-1, determine what was the applied force on the plate.

Dos placas horizontales y parelelas que estn separadas 0.5 m y tienen agua a 40 C entre ellas estn inicialmente en reposo. Despus se mueve la placa superior con una fuerza tal que la capa superior de agua alcanza una velocidad de 0.25 m/s. Si la viscosidad del agua a esta temperatura es de 6.53x10-4 kgm is!, determine la cul fue la fuerza aplicada en la placa. Seleccione la respuesta correcta: O 3.27x10-4 kgm 152 02.84x10-4 kgm 1s2 O 5.42x10-4 kgm 152 4.57x10-4 kgm-152
