The following marks were recorded on air table where the time constant is adjusted at 100ms: A1A2A3 A4 A5 A6
A1A2=4cm A2A3=8cm A3A4=12cm A4A5=16cm A5A6=20cm
a) Find the average speed of the puck between A2 and A6.

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
