We are building EduLadder(ELADR) - Protocol

The Eladr Protocol is a decentralized, security and efficiency enhanced Web3 noSQL database powered by IPFS as the data storage layer https://ipfs.io/, and the Cardano block chain as the rewards token platform, https://cardano.org/. It provides a JSON based, IPFS layer 2 solution for data indexing and retrieval in an 'append only' file system built with open source Node.js API libraries.

The ELADR token was designed to incentivize and reward community members as a proof of contribution. Token holders are also granted access to EduLadder.com premium features as well as associated ELADR token enabled apps.

A rapid sand filter comprising a number of filter beds is required to produce 99 MLD of
potable water. Consider water loss during backwashing as 5%, rate of filtration as 6.0 m/h
and length to width ratio of filter bed as 1.35. The width of each filter bed is to be kept
equal to 5.2 m. One additional filter bed is to be provided to take care of break-down,
repair and maintenance. The total number of filter beds required will be

Ans. (C) 
Given :
 Flow rate = 99 MLD 
 Rate of filtration = 6 m/h. 
 Total water to be filtered   99 
1.05MLD 103.95 MLD [Addition of 5% to be used for backwashing] 
L = 7.02 m 
Surface area of each filter = 36.504 m2
Total surface area required 3 Discharge through filter / Rateof filtration =  721.875m3
Total no. of filter beds required = 19.77 filters = 20 filters
1 unit is to be added as standby, thus total no. of units(filter beds) required = 21
