A sump pump (used to drain water from the basement of houses built below the water table) is draining a flooded basement at the rate of 0.95 L/s, with an output pressure of 1.55 × 105 Pa. Part (a)  The water enters a hose with a 2.7 cm inside diameter and rises 2.1 m above the pump. What is its pressure at this point, in pascals? You may neglect frictional losses.  Part (b)  The hose then goes over the foundation wall, losing 0.65 m in height, and widens to 6.6 cm in diameter. What is the pressure now, in pascals? You may neglect frictional losses

Storm Sewers and Detention

The storm drains system transports rainwater or stormwater and other runoff from roads, parking lots, and roof downpipes directly to nearby creeks, rivers, or the sea without any treatment.
