Fluid mechanics $!!!$The pipe shown in the figure is not open to the atmosphere at either end. The $x-$ component $($towards the right is positive$)$ of the force required to hold the bend in place is: p$1$A$1-$ p$2$A$2$cos$\backslash$alpha $-\backslash$rho QV$2$cos$\backslash$alpha $-\backslash$rho QV$1$

p$1$A$1+$ p$2$A$2$cos$\backslash$alpha $-\backslash$rho QV$2$cos$\backslash$alpha $+\backslash$rho QV$1$

p$1$A$1+$ p$2$A$2$cos$\backslash$alpha $-\backslash$rho QV$2$cos$\backslash$alpha $-\backslash$rho QV$1$

p$1$A$1-$ p$2$A$2$cos$\backslash$alpha $+\backslash$rho QV$2$cos$\backslash$alpha $+\backslash$rho QV$1$

p$1$A$1-$ p$2$A$2$cos$\backslash$alpha $-\backslash$rho QV$2$cos$\backslash$alpha $+\backslash$rho QV$1$ choose one!!!
