Measure the distance of the water from the board. Your first measurement will be when you first fill the hole. Your water should meet the board.Repeat your measurement every two minutes until you have five measurements.

Measure the distance of the water from the board. Your first measurement will be when you first fill the hole. Your water should meet the board.Repeat your measurement every two minutes until you have five measurements.Each time you take a measurement subtract it from the previous measurement to see how far the water has dropped over that two minutes.Calculate the drop in minutes per inch

ible put a few cm of gravel inside the hole.Fill your hole with water and place a board over the hole as shown in this week's reading materials.Take a picture at this step. Measure the distance of the water from the board. Your first measurement will be when you first fill the hole. Your water should meet the board.Repeat your measurement every two minutes until you have five measurements.Each time you take a measurement subtract it from the previous measurement to see how far the water has dropped over that two minutes.Calculate the drop in minutes per inch.This week's reading materials show examples of how to do this calculation. Average your five drop measurements (minutes/inch).  If the result is between six minutes per inch and 60 minutes per inch, then the soil passes the test, and it should be capable of supporting a perc test.

There are two drums D1 and D2, each of which is filled to the brim with water. Now, a leak is made at the bottom of each of D1 and D2, such that the leak in D1 takes 6 hours to empty it, while the leak in D2 takes 9 hours to empty it. If the capacity of D1 is more than the capacity of D2 by 60%, then find the time after which the volume of water in D2 will be 25% more than the volume of water in D1. hours hours3 hours hours

It takes Tap A 12 minutes to fill a container measuring 8 cm by 10 cm by 18 cm completely while it takes Tap B 15 minutes. How long will it take to completely fill the container with water if both the taps are turned on at the same time and 4 cubic cups of edges 3 cm, filled with water, are poured into the container? Leave your answer in minutes and round off to 2 decimal places.
