How to Find Out the Quantity of Stormwater run-off in a Catchment Area Mathematical Problem: A catchment area of 20 km2 consists of two-thirds rural and one-third urban areas. The rainfall intensity in this area is recorded as 25 mm/hr. Find the quantity of stormwater run-off in the area in litre per second. 'K' for … Continue reading Find out the Quantity of Stormwater run-off in a Catchment Area || Mathematical Problem & Solution ||
Combined Gravity And Pumping System In this system, the treated water is pumped and stored in an elevated reservoir, from where it is supplied to the consumer by the action of gravity. Thus, this method combines pumping as well as gravity flow. This system is fairly reliable. Read more: Function of Storage Reservoir 3 … Continue reading Combined Gravity And Pumping System
5 Function Of Storage Reservoir The storage reservoirs are generally provided in the distribution system to store clear treated water before it is distributed to the consumer. Following 5 functions of the storage reservoir are: 1. They help the pump to run at a uniform rate. 2. They provide the facility of storage of … Continue reading 5 Function Of Storage Reservoir
Biochemical Oxygen Demand (B.O.D) The amount of oxygen required to carry out the biological decomposition of dissolved solids in sewage under aerobic conditions at standard temperature is known as biochemical oxygen demand. It indicates the amount of biologically active organic matter present in the sewage. It is generally less than C.O.D. The B.O.D of water … Continue reading Biochemical Oxygen Demand (B.O.D) And Their Test
