Asliding plate viscometer is used to measure the viscosity of a liquid. the plates are 60 cm square and the gap between them is 0.5 mm. what is the viscosity of the fluid if a force of 80 n is required to maintain a velocity of 3 m/s? group of answer choices

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?
