B): Specify the pressure class for a 16-inch (0.375in wall thickness) liquid seamless-pipeline constructed of steel API 5L-52. In addition, if pipe pressure class is 600, what wall thickness will be required?

Do not type, it should only be handwritten.

A 10,000-gallon water tank atop a building delivers fresh drinking water for itsoccupants. A top-floor resident and a bottom-floor resident are filling their bathtubs.Assuming frictionless pipes and isothermal flow, which one will fill faster?A. top floorB. bottom floorC. the tubs will fill at the same rateD. need more information

##About industrial piping Design a simple and hypothetical piping system that connects equipment (consumers) and that has at least two branches with different diameters from the main branch. The system must have:   A brief description of the system, with the types of energy sources (reservoir, tanks, compressor, boiler, pump...) and which consumers (heat exchangers, tanks, vessels, machines...); Indicate the proper location for the installation of the RELIEF VALVES, DRAINS, VENTS and FLOW VALVES; Indicate the TAGs of the equipment, valves, pipes and devices installed; Define basic operating conditions (temperature, minimum and maximum operating pressure, fluid); Define the basic physical conditions (pipe diameter, material specification); Set the maximum design pressure, to be considered as the MAOP (old and hot).   Based on the developed piping system   Estimate the corrosion allowance for the system (20 years); Calculate the minimum thickness for the pipes; Inform what the…

1. Referring to figure 37.90, a rectangular duct with cross sectional measurements of 20 inch × 11 inch will be the equivalent of a round duct with diameter of.

Draft a sketch of this system describe below

I need help figuring out the remaining parts; also do step-by-step, which is very helpful.

6. The coefficient of friction for a flow through pipe with Reynold’s number 40000 isa. Need density, velocity, diameter, and length of pipeb. Need density, velocity, diameter, dynamic viscosity and length of pipec. 0.0707d. 0.0055

What is the function of the empty pipes that connect from the sanitary/drainage pipes up through the roof of a building?

3. Two bedrooms are 15’x20' and 22' x30', respectively, and same ceiling high 15'. Both rooms need air change rate 10 times/hour. Calculate total required supply air CFM to the rooms and branch standard duct (rectangular shape, height is 10”) size to the room, respectively.
