7 217) The power of a motor pump is 2Xw Hhow much water per minute can the pump raise toheight of 20 mtrs. (given g-10m) |
| Answer» <p>Given, power of pump = 2kW =2000W</p><p>Time (t)= 60sec</p><p>Height (h) =20m</p><p>g = 10m/s2</p><p>As you know, power =work done per unit time.</p><p>Work done = mgh = m ×10×20 =200m</p><p>Therefore, 2000W = 200m/60s</p><p>Therefore, m = 600kg</p><p>So, the pump can raise 600kg of water in one minute.</p> | |
