4) A highway department is considering 2 types of paint for a bridge project. Type A paint costs $65/gallon and covers 350 sqft/gal. It provides protection for 4 years. A worker can apply it at a rate of 80 sqft/hour. Type B paint costs $85/gallon and covers 420 sqft/gal. It provides protection for 5 years. A worker can apply it at a rate of 100 sqft/hour. If a painter wage is $25/hour, which paint should be used to yield the lowest cost for the bridge and why? Consider i=6%.

Part II. Longer problem focused on problem solving multiple steps. This problem will be graded based on process, clarity of work, and correct answer and units. a. A spring is stretched, with a force, F = 442 lbf, along the outside of a pipe as shown with a = 53° and ẞ 69° and the coordinates of the force are (15,37,-71 ). How far does the spring stretch if the spring constant is k=67 lb/in? Hint: The force that stretches the spring is the projected force along the pipe F (x, y, z)

2.10 The flow of a liquid in a 2-in. diameter steel pipe produces a pressure drop due to friction of 72.68 kPa. The length of pipe is 40 m and the mean velocity is 3 m/s. If the density of the liquid is 1000 kg/m², then a) Determine the Reynolds number. b) Determine if the flow is laminar or turbulent. c) Compute viscosity of the liquid. d) Estimate the temperature, if the liquid is water. e) Compute the mass flow rate. A single- cylinder rotational viscometer is used to measure a liquid with viscosity of 100 cP using a spindle with 6-cm length and 1-cm radius. At maximum shear rate (rpm=60), the measurements approach a full-scale reading of 100. Determine the spindle dimensions that will allow the viscometer to measure viscosities up to 10,000 cP at maximum shear 2.11. rate. 2.12. A is being used to transport a liquid food product (p = 1000 kg/m³, µ = 1.5 cP) from pump a holding tank to a filling machine at a mass flow rate of 2 kg/s.
