Assume that the density sea water is 1035 kg/m 3 . 60 cm 50 cm 70 cm 40 cm Fresh Water Sea Water Mercury Air (a) Determine the pressure difference (kPa) between the two pipelines. (b) Can the air column be ignored in your analysis? (c) If the air is replaced with oil of specific gravity 0.72, then what is the pressure difference (kPa) between the two pipelines? Can the oil column be neglected? SP4: A damaged 1200-kg car is being towed by a truck. Assume that friction, air drag, and rolling resistance are negligibly small. (a) Determine the power required (kW) for constant velocity on a level road. (b) How much power is required (kW) for constant velocity of 50 km/hr on an uphill road at 30 with respect to horizontal? (c) Calculate the power required (kW) when accelerating on a level road from rest to 90 km/hr in 12 seconds....
