A vertical U-tube partially filled with alcohol (SG= 0.99) is rotated at a specified rate about its left arm. Compute for the following: (a) angular velocity of the tube's rotation if the alcohol is on the brink of spilling (b) pressure at point B during the rotation of the tube Please provide explanation per line of solution. thanks 10 cm 20 cm B +12.5 cm - 12.5 cm 25 cm

Water at temperature of 20 °C is flowing inside a straight, smooth pipe with flow rate of 0.05 m3/h . With which pipe diameter will the flow transition from laminar to turbulent? Kinematic viscosity of water at 20 °C is 1.005·10-6 m2/s. Round off the answer to one decimal digit in cm, but enter the answer without the unit.

Estimate the capillary depression for mercury in a glass capillary tube 2 mm in diameter. Use surface tension = 0.514 N/m Ans. 5.9 mm
