Para descargar granos de la bodega de un barco se emplea un elevador que levanta el grano a una distancia de 12 m. la descarga del grano se realiza por la parte superior del elevador a razón de 2.0 kg cada segundo y la velocidad de descarga de cada partícula de grano es de 3.0 m/s. encuentre la potencia mínima (en hp) del motor que puede elevar los granos de este modo.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

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