In a cold storage plant, it is desired to determine whether to use insulation two inches thick or three inches thick in insulating the walls of the cold storage ware house. Heat absorb through the walls without insulation would cost P96.00 per year per square meter. A two-inch insulation will cost P30.40 per square meter and will cut out 89% of the loss. A three-inch insulation will cut out 92% of the loss and will cost P65.00 per square meter. Using a life 15 years for the insulation with no salvage value and a minimum attractive return of 8%, what thickness of insulation should be used?

9. The frictional loss in a 385 m pipe is equal to 32 m. If the Reynolds Number of the fluid flowing through the 452 mm pipe is equal to 1547. Compute the kinematic viscosity of the liquid in m2/s Round your answer to 7 decimal places.
When a refrigerant vaporizes, it takes heat from its surroundings. The latentheat of vaporization is the amount of heat needed for the refrigerant tovaporize. When 38.5 pounds of R-124 vaporize at 5°F, the latent heat ofvaporization is 2,721.95 Btu. What is the latent heat of vaporization for 1 poundof R-124 at 5°F?
The uniaxial bar finite element equation can be used for other types of engineering problems, if proper analogy is applied. For example, consider the piping network shown in the figure. Each section of the network can be modeled using a finite element. If the flow is laminar and steady, we can write the equations for a single pipe element as: - q₁ = K(P; — P;) qi q;= K(P; - P;) qj where q; and q; are fluid flow at nodes i and j, respectively; P; and P; are fluid pressure at nodes i and j, respectively; and K is K = πD4 128μL where D is the diameter of the piper, μ is the viscosity, and L is the length of the pipe. The fluid flow is considered positive away from the node. The viscosity of the fluid is 9×104 Pa's. a. Write the element matrix equation for the flow in the pipe element. b. The net flow rates into nodes 1 and 2 are 10 and 15 m³/s, respectively. The pressures at the nodes 6, 7, and 8 are all zero. The net flow rate into the nodes 3, 4, and 5 are all zero.
