1.If the municipal water rate is one dollar per thousand gallons, how many pounds of water are delivered to the customer's house for one dollar?
2.Rainwater from California is said to contain 0.3 mg/L of silica. What is the silica concentration in the rainwater in ppt, ppb, molarity, and% solution
3.A solid cube with a side length of 0.4 ft and a weight of 110 lb slides down a smooth surface that is inclined at 45 degrees to the horizontal. The block slides on a film of oil with a viscosity of 1.85 x 10-2 lb-s/ft2. If the velocity of the block is 1.2 ft/s, determine the thickness of the oil film assuming a linear velocity distribution in the film.
A car dealership offers $2000 cash back; financing at 3.49% APR for 60 months or 0% APR for 60 months when you purchase a car. What is the break even point and when would it be better to choose one option over the other.
Vapour from the second effect is condensed at a pressure corresponding to 325 K. The heat transfer area is 10 m2 and the overall heat transfer coefficients are 3 and 2 kW/m2 in the first and second effects respectively.
A particle which moves with curvilinear motion has coordinates in meters which vary with time t in seconds according to x = 3.3t2 + 3.1t - 5.3 and y = 5.1t - 4.0. Determine the coordinates of the center of curvature C at time t = 1.9 s.
If the elevation difference between the water surfaces is y = 25 + x/11 metres, what minimum pipeline diameter will be required to convey the design discharge? Once your design is complete, determine the actual discharge. The value of x equals 23.
Design a hardwood beam to support a uniformly distributed load of 20 kN over a simply supported span of 8 m. consider bending strength only. Assume that the weight of the beam is 2 kN.
A sled with two runners slides along a thin horizontal layer ofwater between the ice and the runners. The horizontal force thatthe water puts on the runners is equal to 1.2 lb when the sled'sspeed is 30 ft/s.
An underground storage vault is to be constructed to serve as a detention pond for a heavily urbanized area. The walls of the vault will be vertical, but the flow will be sloped along its length to promote drainage.
A column of dimensions 200 X 300 mm has an effective length of 3m. It is reinforced with 6 HYSD bars of 20mm diameter. Determine the safe load the column can carry using working method of design. Using M20 Concrete.
Cylinders C and D are attached to the end of the cable. if D has a mass of 600 kg, determine the required mass of C, the maximum sag h of the cable, and the length of the cable between the pulleys A and B. The Beam has a mass per unit length of 50 kg..
A rectangular channel 2.0 m wide carrying a discharge of 2.5 m3/s is to be fitted with a weir at its downstream end to provide a means of flow measurement as well as to cause heading-up of the water surface.
Calculate the depth h of mud for which the 3m concrete retaining wall is on the verge of tipping about its forward edge A. the density of mud may be taken to be 1760 kg/m3 and that of concrete to be 2400 kg/m3.
A 5-m wide rectangular channel is carrying a flow of 5 cubic meter per second. If the Manning n=0.013 and the bottom slope, So=0.0001, determine the normal depth using a converging iteration.
