Astream of liquid cyclopentane flows at a rate of 0.35 lbm / s into an initially empty container with a volume of 2.0 ft3, placed on a scale calibrated to read weight in lbf. the process takes place at sea level.
when only the empty container was on the scale, the scale reading was 2.50 lbf. estimate the reading 10 seconds after the flow starts.
