There are several ways to go in processing 4x5 sheet film. The Jobo way..in a tube, the Daylight tank way, such as a Combiplan-T tank, and my preferred way, on stainless hangers in deep tanks. I like the "deep" tanks best because I can process lots of film at once. 40 sheets or more, using hangers that hold 4 sheet each of 4x5. Deep tanks are not really "deep", but rather just deep enough to hold the hangers. 3.5 gallons.
OH, and for those who are really on a budget, you "can" develop sheet film in print trays by the shuffle method.
