You have just returned from a long, cold day of fieldwork and are eager to take a nice hot bath. You start filling your bathtub then go to make a cup of tea and forget to put in the drain plug. If the volume of water needed for a bath is 0.30 m3 and the water flows in at a rate of 22 liters/minute and out the drain hole at 5 liters/minute, determine how long it will take to fill the tub to bath level. Density of water 1000 kg/m3

Respuesta :

Answer:

time need = 17.65 minutes  

Explanation:

given data

water flows in = 22 liters/minute

water flows out = 5 liters/minute

volume of water needed for a bath = 0.30 m³ = 300 Liters

Density of water = 1000 kg/m³

solution

we get here time for need to fill bath that is express as

time need = [tex]\frac{volume need}{flow\ rate\ in - flow\ rate\ out}[/tex]   .........................1

put here value and we will get

time need = [tex]\frac{300}{22-5}[/tex]    

time need = 17.65 minutes
