Una lancha se desplaza con una velocidad de 10 m/s cuando el motor deja de funcionar debido a la falta de gasolina. A consecuencia de esto, la resistencia aerodinámica, la aceleración subsecuente está dada por la ecuación a=-0.05 v^2 , en donde la velocidad esta dada en m/s

Fluids at rest possess no flow energy. a)- true b)- false

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.
