Figure P$4\mathrm{.}46$ shows a conduit made of $2-$nominal schedule $40$ commercial steel that

conveys ethylene glycol at a flow rate of $4\frac{l}{s}.$ All fittings are regular and

threaded, and the pipe length is $40$ m $.($a$)$ Calculate the pressure drop through the

system using minor$-$loss values $($K$).($b$)$ Calculate the pressure drop through the

system using equivalent length values. Compare the results. Take the piping system

to be in a horizontal plane and the check valve to be a swing type.
