help - please follow the format given

Consider a horizontal 20 mm diameter pipe section of length 300 mm transporting SAE 10W oil at
20°C. The volumetric flow rate is 0.001 m³/s. Assuming fully developed laminar flow, evaluate:
a. mercury manometer reading, h [mm] (assume píg = 13,550 kg/m³)
b. shear stress at the wall [N/m²]
c. verify that the flow is laminar.

2. The following is the standard format for organizing and presenting the solution to a fluid mechanics
problem. Use this (or similar clear, organized, logical procedure) in your homework.
(a) Problem Description - include the following:
• Given information and basic description.
• Schematic of problem/geometry. Clearly indicate system/control volume considered,
coordinate system, any other relevant information.
• What is to be determined.
(b) List of Assumptions - list all appropriate simplifying assumptions.
(c) Basic Equations - general form of relevant fundamental laws, equations, definitions.
(d) Analysis
clearly describe procedure to apply/manipulate/reduce equations to give solution.
• reference all tables and charts needed for physical properties and other data.
• substitute numerical values into final equations. be sure to specify all units
and unit conversions.
• keep significant figures consistent with given data.
• check solution - correct sign, reasonable numerical values?
• clearly indicate final answer(s) with underline or box.
(e) Discussion of Solution - as needed (what you learned, key aspects of solution, etc).
