Kindly solve Q1 B and A also . Answer required urgently for part b

Q.1 A) A 200ml waste water sample was analyzed for different parameters. Sample was firstly passed through non flammable filter- crucible assembly (weight: 25.439g ) and the assembly was dried (at 105C ) to constant mass of 25.645g. A 100ml filtrate was placed in an evaporation dish assembly (weight: 275.419g ) and dried to 276.227g. Both crucible and evaporation dish assembly were placed in muffle furnace (at 550C ) for an hour. Mass of crucible and evaporation dish assembly was measured to be 25.01g and 275.944 g respectively. Determine dissolve solid, suspended solid, suspended volatile solid and dissolve volatile solid in mg/L. (4) B) Calculate removal efficiency of settling tank for loading rate of 2.4102m/min. Column study for 2m height for initial concentration 650mg/L gave following data: (4)
