Calculate speed of efflux of kerosene from an orifice of a tank in which pressure is 4 atmosphere .Density of kerosene is 0.72 kg per litre .One atmosphere `=1 kg f cm^(-2)`.

Calcualate speed of effux of kerosene from an orifice of a tank in which in the tank if therre contaning water has an orifice of an tank in which pressure is 4 atmosphere .Density of kerosene is 0.72 kg per litre .One atmosphere =1 kg f cm^(-2) .

Calculate the velocity of efflux of kerosene form a tank in which the pressure is 4xx10^(5)"N m"^(-2) above the atmospheric pressure. The density of kerosene is 800 "kg m"^(-3) [Hint: v=sqrt(2gh) ]

Find the velocity of efflux of water from an oriffice near the bottom of a tank in which pressure is 500 gf//sq cm above atmosphere.

At What velocity does water emerge from an orifice in a tank in which gauge pressure is 3 xx 10^(5) Nm^(-2) before the flow starts ? (Take the density of water =1000 kg m^(-3) .)

Calculate the velocity with which water emerges from an orifice in a tank if the gauge pressure is 2 xx 10^5 N/m before the flow starts.

At what depth in fresh water the pressure on a diver is one atmosphere ? [Density of water = 10^(3)kg m^(-3), Normal pressure =10^(5)Pa, g =10 ms ^(-2)]

The solution containing 4.0gm of a polyvinyl chloride polymer in 1 litre dioxane was found to have an osmotic pressure 6.0xx10^(-4) atmosphere at 300K ,the value of R used is 0.082 litre atmosphere "mole"^(-1)K^(-1) .The molecular mass of the polymer was found to be

If the water emerge from an orifice in a tank in which the gauge pressure is 4xx10^(5) Nm^(-2) before the flow starts, then what will be the velocity of the water emerging out ? Take density of water is 1000 kg m^(-3)
