Compatibility between the stimuli and response is an important factor in designing controls and motor activities. define the type of compatibility (spatial, movement, conceptual) in the examples below: red, yellow, green traffic meaning danger, caution, and safe aircraft engines, each engine control should be consistent with engine location turning a horizontal steering wheel clockwise, vehicle turns right

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.
