Please, solve this question with solution steps without explanation

P6.14 A spillway model is to be built to a geometrically similar scale of 1/50 across a flow of 600 mm width. The prototype is 15m high and maximum head on it is expected to be 1.5m. What height of model and what head on model should be used. [Hm=0.3 m) ii) If flow over the model for a particular head is 12 Us what flow per meter width at prototype is expected? = 7071

Answer 1

Ans! Given that Geometrically scale is to width Goomm. The Prototype -high 1sm. Man. head l.gm To calculate the height of model: In: HP : 50 = He 50 lilm 15 : 0.3m. Hom: 0.3m. To calculate the head to be used on the model: hmi 1.5, 0.03m 50 1) To Calculte the flow over the Prototype: () Qp = (4)%9Qm - 502x12 : 212:13610045

To calculate the flow Per meter length: Qp =- 212.13 x 100419 30m = 7071.06 l/sim.
