I'm trying to read the flow chart for a submersible water pump. x-axis is gallons per min. y-axis is total head. There are two curves on this graph - one labled TH-Q and the other labled EFF. What do the lables for these two curves mean?

Water flows through a pipe AB 1.2 m diameter at 3 m/s and then passes through a pipe BC 1.5 m diameter. At C, the pipe branches. Branch CD is 0.8 m in diameter and carries one third of the flow in AB. The flow velocity in branch CE is 2.5m/s. find the volume rate of flow in AB, the velocity in...

I have a question about heat exchangers. I have two pipes that have cold water flowing through them. I know their inside and outside diameters as well as their length. I know the exit temperature of the water but not the initial temperature. There is hot steam passing over the pipe that I also...

mechanical vibration, please help with the attached problem

2. Consider a concentric tube heat exchanger with an area of 50 m2 operating under the following conditions: Hot fluid Cold fluid Heat capacity rate, kW/K 6 3 Inlet temperature, oC 60 30 Outlet temperature, oC - 54 a. Determine the outlet temperature of the hot fluid. b. Is the heat...

Hi. I need help with this problem.

is there any difference between the stresses measured at the top of the beam and at the same location on the bottom of the beam?

V= 2t/(1-0.5x/L) where V=velocity, t=time

a beam consists of three planks connected as shown by 3/8 in diameter bolts spaced every 12in.along the longitudinal axis of the beam.knowing that the beam is subjected to a 2500lb vertical shear,determine the average shearing stress in the bolts

block mass = 200 kg is sitting on a smooth surface F1= 500 N F2 = 650 N F3 = 900 N FP = concurrent at the center of the block unit vectors are: e1 = 2/3(((rad(3)/2)i) + (rad(3)/2)j + rad(3)/2k e2 = rad(6)/3(rad(2)/2i - rad(2)/2j - rad(2)/2k e3 = 2/3(1/2i + j + k) What is the resultant...
