1.With the use of appropriate graphs, for centrifugal pumps only explain the relationship between pressure and volumetric flow, and power consumed and volumetric flow.
2.In continuos process control a 'PID controller' is installed which uses a combination of proportional, integral and derivative action. Why are these three modes of control used in conjunction?
3.An inductive proximity switch is a device used in valve feedback, describe the construction, operating principle and beneficial features of the switch?
4.A 40 KVA 3300/240V.50Hz .1 phase transformer has 660 turns on the primary . determine 1, the number of turns on the secondary , 2, the maximum value of flux in the core ?
Determine the number of man-hours required to form the structure using data from R. S. Means or other appropriate reference. What is the difference between labor cost and labor pro-ductivity?
A horizontal curve was designed for a four-lane highway for adequate SSD. Lane widths are 12 feet, and the superelevation is 0.06 and was set assuming maximum fx. If the necessary sight distance required 52 feet of lateral clearance from the roadw..
Calculate the BOD loading and days of winter storage available between the 0.6 and 1.5 m depths, assuming a daily water loss of 0.30 cm by evaporation and seepage.
The structure consists of two uniform members AB and BC, each weight 2kN. The member are pinned to each other at B, and the structure is supported by a pin at C and a surface at A having coefficient of static friction 1.2.
Assuming an isotropic and homogenous hydraulic conductivity of 0.0001 cm/s what is the magnitude and direction of specific discharge (q)?
The void ratio of soil in the borrow pit is 1.12. Estimate the volume of soil (cubic meters) that must be excavated from the borrow pit.
The 30-Mg freight car A and 15-Mg freight car B are moving toward each other with the velocities VA= 20 km/h to the right and VB= 10 km/h to the left. the spring constant on car A is k= 3MN/m.
water flows at a velocity of 25 ft/s at a depth in a rectangular channel 16 feet wide. Determine the downstream depth necessary to form a hydraulic jump, the head loss through the jump and the horsepower dissipated in the jump.
Determine the magnitudes of the additional loads that must be applied at B and F if the resultant of all six loads is to pass through the center of the mat.
A 35 percent-efficient coal-fired power plant with effective height of 100 m emits SO2 at a rate of 0.6 lb/10^6 Btu into the plant. If winds are assumed to be 4 m/s at the stack height and just over 3 m/s at 10 m
