In this section we present figures showing predictions, using formulae (48)-(55) from the previous section, of various design parameters when the gravity ram is used in a tidal situation. The parameters are the required mass of capula and conrod (M_T ), the diameters of the inner cylinder and of the floats (B and B_T) and the volumes of the inner cylinder (V) and of the floats (V_F)- Also shown is the predicted power output. These are all plotted as functions of required flow rate from the pump in tons/day. Figures are presented for working pressures of 500 and 1000 p.s.i. and for available tidal ranges of h = 5m and h = 10m. The graphs shown are for the case when the floats provide a maximum possible upthrust four times the necessary minimum (Q = 4). With this choice of θ the ram makes use, by equation (16), of 80% of the available tidal range: i.e. the corresponding values of H (travel of ram) are 4m and 8m, respectively.
Figures 6-17 show the predictions for a working pressure of 500 p.s.i., and Figures 18-29 for a working pressure of 1000 p.s.i. Within these groupings the first six graphs (6-11 and 18-23) are for a tidal range of 5m, the remainder for a tidal range of 10m.
