5.

If D is the diameter of upper circular portion, the overall depth of a standard egg shaped section, is

 [A]. D [B]. 1.25 D [C]. 1.5 D [D]. 1.75 D [E]. 2 D.

Explanation:

No answer description available for this question.

 Govinda said: (Dec 22, 2015) Why the depth of sewer is 1.5D?

 Ashish said: (Jan 1, 2016) Because top Dia-D and Bottom Dia D/2. Hence total depth D+D/2 = 1.5 D.

 Asaithambi said: (Sep 22, 2016) Top diameter = D. Bottom diameter = D/2. Total diameter = top diameter + bottom diameter. = D + D/2 = 1.5D.

 Rk Patidar said: (Nov 14, 2016) Top diameter is D or bottom diameter is 1.5 that's why 1.5 D.

 Ankush Kaul said: (Aug 17, 2017) Because egg shape sewer inscribed of two sewers. 1 for sullage and 1 for drainage. Since, dia of sullage sewer is 1/2 * (dia of drainage sewer). Therefore, Accumulated Dia = D+0.5D = 1.5D.

 Ramratan Saket said: (May 15, 2018) Top dia=D, Bottom dia=D/2, So, total dia=D+D/2=1.5D.

 Yogesh said: (Aug 30, 2018) D+D/2. 2d+d/2. 3d/2 = 1.5D.

 Pranab said: (Aug 31, 2018) But here asking for overall depth, not diameter please anyone explain it.

 Sandeep said: (Sep 11, 2020) The overall depth is = 1.5 times of the diameter of circular portion.i.e ( d=1.5D).

 Mahfuz Mazu said: (Feb 19, 2021) Yes, 1.5D is the correct answer.
