could someone help me with this problem 3.6 dealing with Mathcad. thanks

36 We need to find the pressure drop. given by ap- wb 2.in L 1 mi (miles) of water pipe, with pipe diameter D 1 in The veloeity is given by V here Q is the flow rate in the pipe and p is the density of water. The term fis the friction factor, used in calculating the amount of friction Far turbulent flow we can obtain the frietion factor e D 2.51 zlogl 3.7 Revi where Re is the Reynolds number and e 0.01 in is the roughness of the pipe surface. The Reynolds number in turn is given by VD Re where is the fluid viscosity.

Explanation / Answer

in a mathcad worksheet , assign the values of

L = 1 mile

D = 1 inch

Q = 1 gal/min and 4 gal/min for 2 cases.

e = 0.01

Please convert units into one common system

Then Write down the formula for Velocity, reynolds number, friction factor and pressure drop. this will simply give the values respectively.
