Find the most economical design that can estimate the main effects of five factors (each with two levels) and all their two-factor interactions. what is the resolution of this design? if it is known that the level combina- tion +, +, +.+, +) of the five factors can lead to disastrous results (e. g. explosion, burn-out), specify how the design should be chosen.

Explain what it means to view something from a frame of reference. provide an example that illustrates your explanation. (4 points)

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
