A fluid moves through a tube of length 1 meter and radius r=0.002±0.0002 meters under a pressure p=4⋅105±1750 pascals, at a rate v=0.5⋅10−9 m3 per unit time. Use differentials to estimate the maximum error in the viscosity η given by

The  maximum error is  

Explanation:

From the question we are told that

     The length  is  

      The radius is  

        The pressure is  

        The  rate  is  

       The viscosity is  

The error in the viscosity is mathematically represented  as

   Where  

and        

and          

So  

substituting values

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
