answer both accurately.

answer only if u know

Answer 1

solir (1) Given that Needed fire flow = 76380 L/min Sustained for 5 hours maximum daily demand = 1.62 m3/s Design Dischoonge five flow + maximum daily demand fire flow : 76380 for 5 hrs min 76380 # 5*60 3 24 * 3600.*10. fire flow = 0: 2652 m®/s Design Discharge 0.2652 + 1.62 :: Design Discharge = (-8852 m3/s > (2). Given that population of town = 20000 The ang property hold 4 people. property consumption on average - 0.874 day peak day factoy = 18, peak hour factoy = 2.2 from the data, we have properties No. of population The ang property hold of people is of town properties 20000 No. of properties = 5000 4

No. of properties * property Consumption Water demand - on average Water demand 5000 * 0.87 4350 1 day For hourly the water demand pump demand peak hour factor * water demand for day 2.2 * 4350 9570 l/day = Ooll L/s Design discharge OollL ls
