Calculate the speed of efflux of kerosene oil from an orifice of a tank in which pressure is 4 atmosphere. Density of kerosene oil = 0.72 kg /lite.

Calculate the speed of efflux of kerosene oil from an orifice of a tan

1.	Calculate the speed of efflux of kerosene oil from an orifice of a tank in which pressure is 4 atmosphere. Density of kerosene oil = 0.72 kg /lite.
Answer» <P> Solution :` P= 1.03 xx 9.8 xx 4 = 40 . 376 Nm^(-2), rho = 0.72 xx 10 ^(3)kg m ^(-3), H = P//rhog = 0.057m, ` ` v = sqrt( 2gh )= 0. 335 ms ^(-1)`
