Helium is to be compressed from 120 kpa and 310 k to 700 kpa and 450 k. a heat loss of 20 kj/kg occurs during the compression process. neglecting kinetic energy changes determine the power input required for a mass flow rate of 100 kg/min. round your answer to the nearest integer. kw

explanation:

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//

answer: the correct answer for the fill in the blank is rods.

rods are the specialized photoreceptor cells that are present in the retina of human eye. they are responsible for vision in the night time ( also called scotopic vision). they have very low visual acuity and color distinguishing ability.

as they are responsible for vision in night time, therefore they are found predominantly in the nocturnal animals.
