The information presented in this engineering note can be of value to others who wish to predict pumping times and water content of vessels containing G-IO material. Four predictions of the water content of the G-IO in the D-Zero Central Calorimeter (CC) are given. Experience from pumping on the NW A cryostat was used to help predict the pumpdown time required for the CC. The actual pumpdown time and water removal from the CC agrees quite well with those predicted which gives confidence for future predictions done using the information presented in this engineering note. A listing of the predictions and actual CC pumpdown particulars is given
