Question

Given: Water from hose filling container asdescribed.    H2O @ 20 C    Volume = 2 L    Time = 2.85 Seconds Use unity conversion ratios and show all of your work,calculating the volume flow rate in liters per minute and the massflow rate in kg/s. Problem 1-41 2nd Edition Fluid Mechanics, Cengal Cimbala, p.34 Given: Water from hose filling container asdescribed.    H2O @ 20 C    Volume = 2 L    Time = 2.85 Seconds Use unity conversion ratios and show all of your work,calculating the volume flow rate in liters per minute and the massflow rate in kg/s.

Explanation / Answer

volume flow rate in liters per minute volume flow rate = volume/time here, volume flow rate = 2/2.85 liters per sec =>volume flow rate = 2*60/(2.85) liters per minute =>volume flow rate = 42.105 liters perminute the mass flow rate in kg/s the mass flow rate = volume flow rate *mass/volume the mass flow rate = 42.105 *1/1kg per minute [since mass of 1 L of water is 1kg] the mass flow rate = 42.105/60 kg/sec the mass flow rate = 0.702 kg/sec
