1.A venturi water meter with a throatof 6 in registers a presssure head difference of 128 in of water between the inlet and throat. calculate the quantity of flowthrough the meter using a discharge coefficient of.93.
2.a rapid mix tank equipped with mechanical mixers will be used to mix the coagulant alum into water at 10 degree in 10 seconds with a root mean velocity gradient of 800s^-1 for a flow of 10 mgd. find the power of the mixer motor assuming it oprates at 70% officeiency.
