Water is flowing down through the pipe shown in the drawing. Point A is 0.410 m higher than B. The speed of the water at A and B are vA = 5.00 m/s and vB = 3.80 m/s. Determine the difference PB - PA in pressures between B and A. The density of water is 1.00x10^3 kg/m3.

• physics -

using the formula :P+rho*g*h + 1/2*rho*v^2=0
calculate: PA= -16518
PB = -7220
PB-PA=-7220-(-16518)=9298
