100 cm Closed - 40 cm The tube shown in the figure is filled with water. What is the pressure at the top of the closed tube? PaQuestion. We were asked to calculate the pressure at dosed End ie. at A. Now, we know that at Equal h=0. 6 m = 60 cm. verticle heights me preencure is e. closed same in liquids . A => brenscore at B = bunure at A Now we are neglecting the atmostphoric presure at the open End . Hence we are only callwanting Gauge pressure at B. i .e . PB = PA = Pgh P = looo kg 2 9 = 9.81 mls 2 = 10 00 x 9. 81 X 0 . 6 h = 0.6 m. PA = 5886 Pa. If we the g = 10 mls 2 (Because g is not mentioned). PA = 6000 Pa. Now, If we take atmospheric bunwere into account. Po = PA = Atmostphuc Brenwire + PA = 101325 + 5886 = 107221 Pa. / 1. 07 x105 Pa. Hope , mis matches me
