4. A give soil has a CEC of 12.50 cmol of charge per kg of soil. If 70%, 15%, 10% and 5% of the CECis occupied by Ca+2, K+1, Mg and Na+1 , respectively, calculate the weight (grams) of Ca, K, Mg and Na in the soil.

5. A given soil contains the following colloids: 1.0% humus (CEC=200), 30% kaolinite (CEC=5), 5%smectite (montmorillonite) (CEC=80), 10% illite (CEC=20), 5% mica (CEC=70) and 49% sesquioxides (CEC=2). Calculate the CEC of the soil? Which colloids contributed the most and which contributed the least? (All CEC are in molc/kg soil).

Q1) Design a concrete mix by using ACI Method of Mix Design having 28-day characteristic mean strength of 27 MPa for a deck of a residential building at Nebraska. Dry weather and gradually warming temperatures may be expected throughout the working week. Fresh concrete composed of a slump of 90 mm and maximum aggregate size of 25 mm. Determine the amount of water reducing admixture to be used for 0.24 % and 0.65 %. Deck is a flat surface capable of supporting weight, similar to a floor, but typically constructed outdoors, often elevated from the ground, and usually connected to a building. Decks that need piers or footings must have them installed below the frost line. This will keep the piers from heaving up out of the ground from the strength of the freeze. Reinforcing steel will help keep the piers from cracking. The freeze or frost line is the depth to which the soil freezes or has been known to freeze at some point in the past. It is absolutely critical that the foundations of buildings extend below this point in a soil profile. Except for a few arid locations, soils typically contain water and this water expands approximately nine percent in volume when it freezes. The frost line depth is not consistent around the nation because there

is such a dramatic difference in climate from state to state. Deck is composed of 2.5 cm reinforcement and there is no need for piers. The material properties are as follows:

For Coarse aggregate: SSD bulk specific gravity: 2.75, absorption capacity = 1.5 %, total moisture: 2.5 %, Dry-rodded unit weight: 1514 kg/m³.

For Fine aggregate: SSD bulk specific gravity: 2.65, absorption capacity = 1.0 %, surface moisture: 3 %, F.M: 2.6.

Cement: Type V, Sp.Gravity: 3.23

Probability constant: 1.22 and standard deviation: 2 MPa

write a program that finds the average of all positive, non-zero values found in a given array of doubles and prints that to the console. Any negative or zero values do not contribute to the average. The program should use the array provided in the code, and you may assume that it has already been populated with values. The results should be printed out to the console in the following format:

“Average: ”<<average value>>

Values denoted in “<< >>” represent variable values, and strings in quotations denote literal values (make sure to follow spelling, capitalization, punctuation, and spacing exactly). Also, if there are either no non-zero or positive in the array then print out the average value as “0.0”.

Solution Tests:

• Does the solution compile?
• Does the solution have your name in the comments?
• If the array has the values {2.0,-4.0,-6.0,8.0,11.0} does the program print out:

Average: 7.0

• If the array has the values {-1.0,5.0,-10.0,2.0,-20.0,0.0} does the program print out:

Average: 3.5

• If the array has the values {-5.0,-4.0,-3.0,-2.0,-1.0} does the program print out:

Average: 0.0

C -Language Create a simple calculator that performs addition, subtraction, multiplication, and division. Your program should prompt the user for the operation they wish to perform followed by the numbers they wish to operate on. You should have a function for each operation and use branches to determine which function to call.

I need this to make any integers given, into decimal numbers, such as 3 to 3.0, or 2 to 2.0, also, so that I can multiply or add things like 2.5 + 3.0 or 2.5 * 2.5, etc.
