Fluid Materials

In general terms, anything that flows can be termed as a fluid. In other words, a fluid is any substance that cannot resist shear forces and deforms continuously under the application of external shear forces. Fluid materials differ completely from solid materials such as metals and alloys. For instance, if we consider two infinitesimally small cross-sectional areas of fluid materials and solid materials, and apply shear forces to these elements, both the elements will undergo deformation. Upon releasing the shear force, the element of the solid materials will regain its original orientation, but the element of the fluid materials will keep on deforming continuously under the action of the shear force.

You are given the following information about a dry-batchpaving operation. You are going to use one mixer that has aservice rate of 30 services per hour. The dry-batch trucksyou use for bringing concrete to the paver have an arrivalrate of 7.5 arrivals per hour. Each truck carries 6 cubic yardsof concrete. You have a total amount of 13,500 cubic yardsof concrete to pour. You rent a truck at $15 per hour and thepaver at $60 per hour. If the job takes more than 80 hours,you pay a penalty of $140 per hour owing to delays in jobcompletion. On the basis of least cost, determine the numberof trucks you should use. Plot the cost versus the numberof trucks used.
Calculate the cost per cubic yard to place concrete using each of the alternatives described. The work in both cases consists of placing 140 cubic yards of concrete in footings. a. Using a crane and bucket at a price of $225 per hour, including an operator, with a crew consisting of 6 laborers, a cement finisher, and a foreman. The concrete will be placed in 7 hours using this setup, and transportation of the crane costs $390. b. Using a concrete pump at a price of $295 per hour, including an operator and a crew consisting of 5 laborers, a cement finisher, and a foreman. With this setup, concrete is placed in 6 hours and transportation of the pump costs $290.

A transit concrete mixer truck gets stuck in traffic and arrivesjust after the maximum time allowed for fresh concrete. Theproject superintendent rejects the concrete, but the driverinsists that it is visible still in good shape. However, becausethe superintendent refuses to accept the concrete, it is dumpednearby the project. Who should pay for this concrete?
Calculate total cost per cubic yard of concrete, given the following: Concrete materials and batching costs = $70/cy Trucking = $6.00/cy Paving equipment = $340.00/hr - Paving labor = $500.00/hr Paver production = 120 cy/hr Incidentals $4.00/cy Overhead and profit = 20% of direct costs 1.87.0 = O2.106.8 O 3.104.4 4.99.6

A concrete pump of 100 m3/hr maximum output (efficiency 54 min/hr) is used to place 270 m3 of concrete. The concrete is supplied by 9 m3 truck mixer arriving to the site every 12 min. How many hours the placing is required?
Hi, I need this asap pls. Thank you so much.
Calculate number of transit mixers (TM) required for transporting concrete from central batching plant to site. The cycle time data of a 6 m³ typical transit mixers is given below: O Loading time of TM = 6.0 minutes. O Travel time of loaded TM to site= 30 minutes. Average waiting time at site = 5.0 minutes Discharge time of concrete at site through concrete pump = 15 minutes. Travel time for return trip = 24 minutes. If the central batching plant having average output of 60 m³/hr is to run continuously, work out the requirement of no. of concrete pumps and TM.
Based on the equipment prices given in Figure 10.1 and the crew described in Figure 10.5, calculate a price per cubic yard to strip topsoil from small areas when the expected productivity is 45 cubic yards per hour.
