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...

Tips for asking Questions
- Provide any and all relevant background materials. Attach files if necessary to ensure your tutor has all necessary information to answer your question as completely as possible
- Set a compelling price: While our Tutors are eager to answer your questions, giving them a compelling price incentive speeds up the process by avoiding any unnecessary price negotiations
1. Can you help me with this Thermodynamics question:
- A closed, rigid tank whose volume is 1.5 m3 contains refrigerant 134a, initially a two phase liquid-vapor mixture at 10C. The refrigerant is heated to a final state where temperature is 50C and quality is 100%. Locate the initial and final states on a sketch of the T-v digram. Determine the mass of vapor present at the initial and final state, each in kg.
2. Can you show me step-by-step how to determine the phase or phases in a system consisting of H2O at the following conditions and sketch p-v and T-v diagrams shown the locations of each state?:
- a) P= 80 lbf/in^2, T= 312.07 F
- b) T= 400 F, P= 360 lbf/in^2
