How to start the operation of HVAC sizing of a building?

Customarily, people tend to spend most of their time indoor at home and in the workplace. As such, it is essential to improve Indoor Environmental Quality (IEQ) to enhance occupants’ health and wellbeing. Recommend three (3) IEQ aspects including daylighting and rationalise their interrelations with design decisions supported by scientific evidences or means to secure office building users’ comfort, health, and productivity.

For an opened joint with infill materials (i.e. filled joints), its shear strength is affected by the type and thickness of the infill material. State two (2) types of infill material and explain how each type affects the strength of the filled joint.

Fixed load bending moment MD = 130 kN·m, live load bending moment ML = 140 kNNm
Rectangular short beams with width b = 400 mm and depth h = 600 mm are designed as follows:
Determine design suitability. Assume the coating thickness is 40 mm.(f ck = 27 MPa, f y = 300 MPa , tensile reinforcement 6-D22, shear reinforcement D10)

Discuss the suitability of the following rock types in terms of their potential for Alkali Silica Reaction (ASR) when used as aggregates in concrete mix

. i) Granite

ii) Rhyolite

Explain the likely physical and chemical reaction of the limestone due to the effect weathering process, and give example.

The rock mass and material characteristics of an igneous rock are greatly influenced by the chemistry of magma and the tectonic settings in which they are formed. Based on the statement given, answer the following questions. a) Briefly explain the main difference between the texture of volcanic and plutonic igneous rock? (3b) Discuss how silica content affects the chemistry of magma? c) Explain the difference between the typical rock mass characteristics of plutonic and volcanic igneous rock? (d) Discuss the suitability of the following rock types in terms of their potential for Alkali Silica Reaction (ASR) when used as aggregates in concrete mix. i) Granite ii)

Please don't leave any questions to answer. If you are waiting for great feedback then that should be me. This questions are from surveying and spatial science

a). You are working in the Environmental Management section of a Local Government Council. Your Local Government area includes approximately 100 km of coastline, comprising a mix of beaches, coastal dunes, rocky shores and headlands. Some regions of the coastline are considered highly vulnerable to the effects of climate change. Along the coastline there are beachside communities, agricultural activities and natural bushland.

Carefully consider the environmental monitoring that may need to be undertaken in order for your Council to measure and manage the impacts of climate change. List and describe the surveying and spatial technologies and methods that might be required to collect, manage and analyse the spatial data required by the Council.

b). You have been employed by a company that provides services to the farming/agriculture sector: including grazing (cattle and sheep), broad acre cropping (grains), and intense, high-value horticulture (irrigated crops such as lettuce, cherries, stone fruit). The company has identified spatial technologies as an emerging opportunity to provide new services to their clients. List and describe four examples of how different spatial technologies can be applied to farming/agricultural business

Consider a residential building with 5 floors with two homes at every flat each having 3 m height. You want to design such a piping system that provides the same mass flow rate to all floors with same outlet pressure. Come up with such a piping system that uses only one pump for the whole installment. Draw your system, make your assumptions, and show your results with a case study.

It is necessary to pump twice as much water as can be handled by an existing small pump, which is now 5 years old. This pump can be sold now for $1200 or kept for 5 years, after which it will have zero salvage value. Operating expenses are $2500 per year.

If the pump is kept, a similar extra one must be purchased for $3500, with operating costs of $2000 per year; its salvage values after 5 and 10 years are the same as for the original (existing) pump.

A large pump, equal in capacity to two of the smaller pumps, costs $6200, with operating expenses of $4200 per year.

New machines have economic lives of 10 years with 1800 and zero salvage values at year 5 and year 10 respectively. Determine the best course of action if the MARR is 10%.

Interns,

Mr. Howell, the prestigious founder and owner of our company would like you to perform an analysis on the company’s weekly revenues. He is requiring that the current weekly marginal revenue be at least $5,000 per week and if it is not currently at that level how fast should sales be changing to reach the target marginal revenue level. The most current information regarding weekly revenues can be found in Mr. Howell’s email below.

To be solved using derivatives.

“Mr. Kleppin,

It has come to my attention that our weekly marginal revenues may not be at the minimum level of $5,000 per week as I required. According to the sales report, we are currently selling 1,000 DVD’s per week and sales are currently rising by 200 DVD’s a week (gotta love the Marvel Universe! Customers can’t get enough!). They also inform me that our current selling price is $20 and that the price is dropping by $1 per week to encourage more sales. I would like you, Mr. Kleppin, to give the interns a chance to earn one of the 10 available positions at the end of their internship by giving them the opportunity to do the analysis. Again, I need to know if we are at the minimum level of $5,000 per week in marginal revenue, and if not, at what level should our sales per week be at so as to achieve the minimum marginal revenue level.”

make a peg adjustment for the following notes:

When the wye level is at 1, the rod readings on P and Q are 0.750m and 2.766m respectively.

When the wye level is at 2, the rod readings on P and Q are 1.906m and 3.798m respectively.

Point 1 is on the same line PQ and midway between P and Q. Point 2 is on the same line as P and Q but not between them. Point 2 is 40m from P and 260m from Q. With the wye level at point 1

Determine the following for a level sight:

a.) Rod reading (m) at P

b.) Rod reading (m) at Q

Imagine that you are assigned in a road way project and you found out that the soil is a non-cohesive week soil, design a work plan in order to stabilize this soil, taking into account the cost, materials, labor and the strength to be obtained
