Therefore, it is notnecessary to lift the water above the required elevation. Of course, forthe same head, a larger diameter tympanum-wheel is needed than noria-wheel,i.e., the tympanum diameter must be slightly more than twice the head. Dueto this size requirement, tympanums are usually limited to lifts of lessthan 10 ft.Several other names which are applied to this device include:sakia (Egypt) tabootsagia tanabish (Eglwt)sagiyasakiyehdrum-wheelwaterwheeltablia spiral wheelscoop-wheel
