A cylindrical can of height h and base area S is immersed in water to a depth h0 in figure. A small hole of area s appears in the bottom of the can. Determine how quickly the can sinks.
None of these
The level of water in the can will rise as much as the can sinks
in the water.
An isosceles triangle of base 3m and altitude 6m, is immersed vertically in water having its axis of symmetry horizontal as shown in figure. If height of water on its axis is 9m, the total thrust on the plate is
A liquid of density ðœŒis compin a rectangular box. The bletely filled ox is accelerating horizontally with acceleration 'a'. What should be the gauge pressure at four points P, Q, R, S ?
A rectangular box containing water is accelerated upwards at 3m/s2 on an inclined plane making 30Ëš to the horizontal. The slope of the free liquid surface is :
The speed of liquid through the siphon is:
Pressure at point B is
Pressure at point C is
What is the gravitational potential energy of 8 cm3 of blood in a 1.8-meter tall man, in a blood vessel 0.3 m above his heart?(Note: The man’s blood pressure is )
The blood pressure in a capillary bed is essentially zero, allowing blood to flow extremely slowly through tissues in order to maximize exchange of gases, nutrients, and waste products. What is the work done on 200cm3 of blood against gravity to bring it to the capillaries of the brain, 50 cm above the heart?
During intense exercise, the volume of blood pumped per second by an athlete’s heart increases by a factor of 7, and his blood pressure increase by 20 %. By what factor does the power output of the heart increase during exercise?
The sphere of an ancient water clock jug is such that water level descends at a constant rate at all times. If the water level falls by 4 cm every hour, determine the shape of the jar, i.e., specify x as a function of y. The radius of drain hole is 2 mm and can be assumed to be very small compared to x.
