Three piezometers A, B, C are 2000 m apart from each other. Piezometer B is located due north of Piezometer A, and C to the west of line AB. The ground surface elevation, the bottom elevation, and depth of water in each piezometer is given below: At A At B At C
Ground elevation (above mean sea level) (m) 340 300 360
Piezometer bottom elevation (m) 100 90 110
Depth to water level in piezometer from ground surface (m) 50 30 80

Required:
Estimate the direction of the groundwater flow that is perpendicular to the contours.

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
