Here, u is velocity of fluid,  is viscosity, and p is the fluid pressure,  
The flow of the fluid where the plate is moving and the bottom plate is fixed, 
 
 
 
 
Hence the upper plate is moving with the velocity and the lower plate is fixed, the 
pressure gradient across the flow will be negative and the magnitude,

maintaining along with its flow direction, 
According to the Navies-Stokes principle,
