need to write energy equation, considering pump and you have to guess your volumetric flow rate by using chart (b) and equation found. Then you can find the pump power requirement by using efficiency of pump, stated in chart (b).

You decided to open your facility to produce VAP beds and now you are ready to bring in all equipment, labor force, machines, raw materials and so on to your factory. However, you have to determine the space requirements and all allowances for these production factors in order to design your layout efficiently. In deliverable 2, you had developed an operations chart by defining the operations with their associated times. As of today, the management revised all operations charts and defined your operations chart in the system, meaning there are processes, machines that are required for each process, prerequisites for each machine and number of people required. Now, it is time to use all the information you developed in order to solve the problems in the project in Deliverable 3.


1. Write your processes, their task times and their predecessors using prior information from Project Deliverable 2.


Find cv and cp for a certain fluid if the properties are related as follows: u = (196 + 0.718t) KJ/kgm and pv = [0.287(toc + 273)] where v is in m3/kgm and p is in KN/m2.


For cretain ideal gas, R = 0.32 KJ/kgm - K and cp = 1160 J/kgm- K. (a) Find cv and k. (b) If 6 kgm of this gas undergo a reversible nonflows constant pressure process from V1 = 2.1 cu. m, p1 = 0.7 MPaa to a state where T2 = 830 K, find ▲H, ▲U, and Q and W.


A 60 kgm body has a potential energy of 135 Kcal with respect to a datum plane X and a potentiaal energy of -99 Kcal with respect to datum plane Y. If the local acceleration of gravity is standard, compute the relative position of plane X relative to plane Y. Resolve the problem if g = fps2.


A closed system undergoes a frictionless process from 200 psia and 3 ft3 during which the product pV1.3 remains constant. How much work does the system do if the final pressure is 40 psia?


A piston-cylinder arrangement contains a gas at P1 = 600 KPa, V1 = 0.10m3 and expand to V2 = 0.5 m3. Compute the work done by the gas if the process follows the relation (a) pV1.4 = c, and (b) p = -300V + 630, where p is in KPa and V in m3.


A certain fluid in a closed system initially at a pressure of 200 psia and having a volume of 3 ft3 undergoes a frictionless process during which the product pV1.3 = C. If p2 = 40 psia, compute the work done by or on the system.
