A stone weighs 90 N in air and when immersed in water it weighs 50 N. When the metacenter and center of gravity of any floating body coincide, the floating body will be:. An Aluminum sphere dipped into water at 10 degrees centigrade, if the temperature is increased, the force of bouncy will. A cylindrical wooden block of length 50 cm is floating in water in such a way that its axis is vertical.
The submerged depth, i. Which of the following statements is more relevant in the context? Suggested Test Series. General Science Booster - Get your knowledge on track. Suggested Exams. More Fluid Mechanics Questions Q1. A straight m long raw water gravity main is to carry water from an intake structure to the jack well of a water treatment plant.
The required flow through this water main is 0. Allowable velocity through the main is 0. An incompressible fluid is flowing at a steady rate in a horizontal pipe. For both the parallel pipes, assume the head loss due to friction only and the Darcy-Weisbach friction factor to be the same.
Three rigid buckets, shown as in the figures 1 , 2 and 3 , are of identical heights and base areas. Further, assume that each of these buckets have negligible mass and are full of water. The weights of water in these buckets are denoted as W1, W2, and W3 respectively. Also, let the force of water on the base of the bucket be denoted as F1, F2, and F3 respectively. The option giving an accurate description of the system physics is. A rectangular channel having a bed slope of 0.
Given that the normal depth of flow ranges between 0. The minimum width of a throat in m that is possible at a given section, while ensuring that the prevailing normal depth is not exceeded along the reach upstream of the contraction, is approximately equal to assume negligible losses. The pipe carries an incompressible fluid at a steady rate of 30 litres per second. The difference of pressure head measured in terms of the moving fluid in between the enlarged and the throat of the venturimeter is observed to be 2.
Taking the acceleration due to gravity as 9. Calculate the buoyant force in air on a kilogram of gold whose density is about 19 grams per cubic centimeter. The density of air is 1. Remember that the buoyant force is equal to the weight. Which of the following are acceptable units for buoyant force? Choose all that apply. Seawater exerts both an upward buoyant force of N on the sub, as well as a downward resistive force of N.
