Firefighters connect a fire hose to a hydrant and lift the other end of the hose into the air to attack a fire in an upper floor. Just below the hydrant the gauge water pressure is 148 kPa, the pipe has a diameter of 6.0 cm, and the volume flow rate through the pipe is 0.04 m3/s. If the gauge water pressure is zero at the high end of the hose, which has a diameter of 5.0 cm, to what height did the firefighters lift the hose?

    Meruem and Maria each set a disc spinning on a rod. Meruem’s disk has a mass of 0.5 kg with a radius of 15 cm and spins about the axle at a rate of 100 rpm. Maria’s disk also has a mass of 0.5 kg, but a radius of 20 cm, and it spins in the same direction as Meruem’s at a rate of 150 rpm. The two discs then collide and stick together. What is their final rotational speed in rad/s?

In the figure, a cylindrical L-shaped pipe is connected to a cylindrical tank in the atmosphere near the surface of the Earth. The absolute pressure at point B is 150 kPa, and the density of the oil is 900 kg/m3. What is the mass of the floating piston? (The figure shows the system which is filled with oil and consists of a hollow closed vertical cylinder and an L-shaped pipe connected to the middle of its lateral surface. The cylinder has a height of 60 centimeters and a base diameter of 20 centimeters. The top base of the cylinder is marked A. The bottom base of the cylinder is marked B. The pipe has a diameter of 4.0 centimeters. The vertical part of the pipe has the oil column of 100 centimeters with a piston on it.)

A client is receiving dantrolene sodium (Dantrium) PO for malignant hyperthermia. The maximum safe dose is 8 mg/kg/day in 2 divided doses. The client currently weighs 50kg. What is the maximum safe dose the practical nurse should calculate? (round to the nearest whole number)
