1.The acceleration of a particle along a straight line is defined by a=(2t-9)m/s^2, where t is in seconds. At t=0, s=1m, and v=10 m/s. When t=9s, determine the particles position, the total distance traveled, and the velocity.
2.A car starts from rest and moves along straight line with anacceleration of a = (3s-1/3)m/s2, where s is in meters. Determine the car'svelocity and position when t = 6s
3.A canal cut in rock (n= 0.030 is trapezoidal in section with the bottom width of 6.10m and side slopes of 1 on 1. The allowable average velocity is 0.76 m/s. What slope will produce 5.66 m^3/s
Given the data , design a section of sanitary sewer to carry these flows at minimum velocity of 2.5 fps. Assume that the minimum depth of the sewer below the street must be 8.5 ft and that an n value of 0.013 is applicable.
To orient a transit in azimuth when the transit is set up over a point D, a backsight is taken to another point, C, with vernier A set at the azimuth of the line CD and with the telescope in its inverted position
What are the basic components of a building. Discuss the main requirements of each part to fulfill its primary function.
Deisgn a thrust block needed to resist the force generated by a 45 degree flanged regular elbow which carries a flow of 14 cfs. The diameter of the fitting narrows from 24 inches to 18 inches and the inlet pressure is 100 psi.
Calculate the minimum flow rate (m^3/hr) of river water needed to acheive pre cooling hot, pasteurized liquid prodcut assuming that 10% heat is lost to the surroundings during exchange and that the water temp after cooling should not exceed 25 deg..
water with a static pressure of 1.96knm2 flows through an 800 mm diameter pipe. a pitot tube pressure gage in this pipe
If the tank is 2 meters deep and the particle enters the tank at the surface of the water, what is the longest amount of time that the particle can take to settle, if it is to be removed
A 400 lb crate is on a 20 degree incline. If a 120 lb horizontal force (P), pushes on the crate (upwards), determine the normal and frictional forces acting on the crate. Take friction of surface = 0.3 and friction of k = 0.2?
A reverse osmosis plant desalinates 5*10^6 L/day of feedwater containing 1500 mg/l of salt, yeilding 3*10^6L/day of product water with 75 mg/l of salt. What would be the salt concentration be in the brine
Our ESP is collecting 95% of the particles in our exhaust stream. We are under pressure to improve its performance. It has been suggested that if we were to cool the inlet gas from the present 600°F to 250°F
An Engineer is considering the development of a small wind turbine (D=1.25m) for home applications. The design wind speed is 15 mph at T=10C and p=0.9 bar. The efficiency of the turbine is n=20% meaning that 20% of the kinetic energy in the wind can ..
A pre- engineering base line was run down a very steep hill.rather than measure horizontaily down hill with steel tape: surveyor measured the vertical angle with the theodolite and slope distance with 16m steel tape.
