When scientists and engineers develop solutions to problems, they use a series of steps that are part of the engineering design process. One version of the process is shown in this flowchart. Drag the correct option into each box to complete the flow chart. Identify a Need → ( ) → ( )→Choose a Solution to Test→Design a Prototype→( ) → ( ) →Redesign as Needed→Implement the Solution

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
