Question 8
A house-top water tank is made of flat plates and is full to the brim. its height is twice that of any side. The ratio of total thrust force on the bottom of the tank to that on any side will be:
Question 9
The flow past the cylinder with the vortex motion causes a net transverse motion. This transverse force is known as
Question 10
A vertical clean glass tube of uniform bore is used as a piezometer to measure the pressure of liquid at a point. The liquid has a specific weight of 15 kN/m3 and a surface tension of 0.06 N/m in contact with air. If for the liquid, the angle of contact with glass is zero and the capillary rise in the tube is not to exceed 2 mm, what is the required minimum diameter of the tube?
