Question 7 :
Consider the equations $P = \displaystyle \lim_{\triangle S\rightarrow 0} \dfrac {F}{\triangle S}$ and $P_{1} - P_{2} = \rho gz$.<br>In an elevator accelerating upward.

Question 8 :
A right angled tube is fixed horizontally on a horizontal surface and an ideal liquid of density p is flowing into the tube at the rate of $Q = 4 m^3/s$ Cross sectional area of the tube at intake and outlet positions are $A = 2 m^2$ and $S = 1 m^2$ respectively. The magnitude of net force exerted by liquid on the tube is (Given that the value of atmospheric pressure $P_o = 4p N/m^2$)
