When a particular discharge is flowing in a horizontal pipe, a mercury-water U-tube manometer connccted to the entrance and throat of a venturimeter fitted in the pipe recorded a deflection of 25 cm. If the same discharge flowed through the same pipe kept at an inclination of 45° to the horizontal, then the corresponding deflection recorded by the U-tube manometer will be-A-25 2 cmB-25/2 cmC-25/2 cmD-25 cm-D-25 cm

Question

When a particular discharge is flowing in a horizontal pipe, a mercury-water U-tube manometer connccted to the entrance and throat of a venturimeter fitted in the pipe recorded a deflection of 25 cm. If the same discharge flowed through the same pipe kept at an inclination of 45&deg; to the horizontal, then the corresponding deflection recorded by the U-tube manometer will be-A-25 2 cmB-25/2 cmC-25/2 cmD-25 cm-D-25 cm

APTITUDE CRACK · Accepted Answer
