A smooth pipe has an inside diameter of 28 mm, is 16 m long, and carries 10C water at a rate of 8 kg/ s What is the pressure drop across the pipe in kPa

A hole is to be drilled as shown by the circle. Using the part geometry shown below, indicate on the part sketch where locator(s) should be positioned according to the 3-2-1 principle. Use dashed lines to indicate locators on hidden surfaces. Also indicate where clamping force(s) should be applied using arrows. Use the minimum number of clamping forces.

Can you please solve for va and vb. This is not what I asked for
