approximately:
A. 5.96psi
B. 8.98psi

ST
proceed straight out the other end at both sites

discharge
B. the fire pump decreases the amount of time it takes to completely dump a load of water and return to
the fill site
C. the cost of an MWS apparatus with a jet-assisted dump is significantly less than the cost of an MWS
apparatus with a gravity dump
D. the flow rate even when the pump is not operating is greatest than the flow rate of an MWS apparatus
K
with a gravity dump - ANS A. the in-line discharged creates a venturi effect increasing the water flow
through the large tank discharge
