Water is pumped through a 60 m pipe of 0.3 m diameter from a lower reservoir to a higher reservoir whose surface is 10 m above the lower one. the sum of minor loss coefficients is kl = 14.5. when the pump adds 40 kw to the water the flowrate is 0.20 m3 /s. determine the pipe roughnes

Which statement correctly describes the relationship between frequency and wavelength?

What causes the formation of ocean currents?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
