Water enters a hydraulic turbine through a 30-cm-diameter pipe at a rate of 1.1 m3/s and exits through a 25-cm-diameter pipe. the pressure drop in the turbine is measured by a mercury manometer to be 1.2 m. for a combined turbine–generator efficiency of 83 percent, determine the net electric power output. disregard the effect of the kinetic energy correction factors. take the density of water to be 1000 kg/m3 and the density of mercury to be 13,560 kg/m3. the net electric power output is kw.

I'm kinda lost ! 1. when marilyn takes her pet dog for a walk, the dog walks at a veryconsistent pace of 0.55 m/s. draw a position-time graph to representmarilyn's dog walking the 19.8 m distance from the front of her house tothe nearest fire hydrant.2. both car a and car bleave school when a stopwatch reads zero. car atravels at a constant 75 km/h, and car b travels at a constant 85 km/h. a) draw a position-time graph showing the motion of both cars. howfar are the two cars from school when the stopwatch reads 2 hrs? calculate the distances and show them on your graph. b) both cars passed a gas station 120 km from the school. when dideach car pass the gas station? calculate the times and show themon your graph.3. the figure below shows the position-time graph showing a shopper'smovement up and down the aisle at a store. a) write a story describing the shopper's movements at the store. b) when does the shopper have a position of 6 m? c) how much time passes between when the shopper enters the aisleand when he gets to a position of 12 m? what is the shopper's averagevelocity between 37 s and 46 s?
