All the above.<\/p>\n<p>The gradient of a sewer is the slope of the sewer pipe. It is important to have a proper gradient in order to ensure that sewage flows smoothly and does not back up. The gradient of a sewer depends on the following factors:<\/p>\n<ul>\n<li><strong>Velocity of flow:<\/strong> The faster the velocity of flow, the steeper the gradient needs to be in order to prevent sewage from backing up.<\/li>\n<li><strong>Diameter of the sewer:<\/strong> The larger the diameter of the sewer, the less steep the gradient needs to be.<\/li>\n<li><strong>Discharge:<\/strong> The higher the discharge, the steeper the gradient needs to be.<\/li>\n<\/ul>\n<p>In general, the gradient of a sewer should be between 0.001 and 0.002. This means that for every 100 feet of sewer pipe, the pipe should slope down by 1 inch. If the gradient is too steep, sewage can erode the pipe and cause leaks. If the gradient is too shallow, sewage can back up and cause flooding.<\/p>\n<p>It is important to calculate the correct gradient for a sewer before it is installed. This can be done by using a hydraulics calculator or by consulting with a civil engineer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Velocity of flow&#8221; option2=&#8221;Diameter of the sewer&#8221; option3=&#8221;Discharge&#8221; option4=&#8221;All the above&#8221; correct=&#8221;option4&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[650],"tags":[],"class_list":["post-7814","post","type-post","status-publish","format-standard","hentry","category-waste-water-engineering","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>The gradient of sewers depends upon A.
