Water flows through a valve at the rate of 1000 lbm/s. the pressure just upstream of the valve is 90 psi and the pressure drop across the valve is 50 psi. the inside diameters of the valve inlet and outlet pipes are 12 and 24 in. the flow occurs in a horizontal plane. determine the loss in available energy units across the valve.

Argon, neon, and xenon are examples of

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?
