A freight elevator, including its load, has a mass of 1 Mg. It is prevented from rotating due to the track and wheels mounted along its sides. The motor M develops a constant tension T= 4.1 kN in its attached cable. Neglect the mass of the pulleys and cables.
Write out the equations of motion for the elevator, and solve for the acceleration.
Then apply the constant acceleration equations to solve for the velocity when the elevator has moved 4 m upward from rest.

The impeller of a centrifugal pump has inner and outer diameters of 15 cm and
35 cm, respectively, and a flow rate of 0.160 m³/s at a rotational speed of
1400 rpm. The blade width of the impeller is 8 cm at the inlet and 3.5 cm at the
outlet. If water enters the impeller in the radial direction and exits at an angle
of 60° from the radial direction, determine the minimum power requirement for
the pump. Take the density of water to be 1000 kg/m³
The minimum power requirement for the pump is 95.51 kW.

The tank water surface is open to the atmosphere, and a sharp-edged 10-cm-diameter orifice at the bottom drains to the atmosphere through a horizontal 80-m-long pipe. The total irreversible head loss of the system is determined to be 1.500 m. In order to drain the tank faster, a pump is installed near the tank exit. Determine the pump head input necessary to establish an average water speed of 6.5 m/s when the tank is full. Disregard the effect of the kinetic energy correction factors.
