During the production of biodiesel, glycerin is a waste product and is collected by gravity separation because its sg (1.26) is much higher than that of biodiesel. glycerin is withdrawn from the bottom of the separation tank through a pipe that has p1 = 350 kpa gage, where d = 70 cm and the flowrate is 680 l/s. find the pressure at section 2, which is 0.8 m higher and where the diameter has been reduced to d = 35 cm. assume the flow is inviscid. (gravity acceleration: g = 9.81 m/s2)

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
