2.) Suppose you are to analyze a cooling system, the room conditions are 75 °F and 50% relative humidity, the SHR is equal to 0.4 and the initially targeted supply temperature is 55 °F. What can be said about this process?
A.) Tadp = 40 °F
B.) The process is simple cooling.
C.) This process has no ADP, cannot handle the latent load.
D.) The sensible load is too high!

3. A conditioned space is to be maintained at 75 F and 50% relative humidity. Mark this state on the chart as ". @P6 RA". The load on this space is known to have an enthalpy to humidity ratio or psychrometric slope of 4000 BTU/Ibm. The supply air is provided at 55 F. Mark the SA state as OP6 SA What is the enthalpy for the SA found by using the chart? What is the humidity ratio for the...
A motel in Miami, Florida has a sensible cooling load of 75 tons and a sensible heat ratio on the building of 0.85. Each of the motel's 100 rooms must be supplied with 30 cfm of outside air to satisfy the local ventilation codes. If the rooms are kept at 75F and 50% R.H., determine: a.) sketch of the system b.) Air flow to the building in cfm (fan size) c.) The mixed air condition-temperature and humidity d.) The cooling...

Problems - A two constant air-volume system with duct reheater similar to the one shown in the Figure is to be designed for Jeddah summer outdoor design conditions of Ta = 40°C & Txt = 24°C. Fifteen percent (15%) of the supply-air mass flow rate to each one is to be fresh air (outside air). The cooling coil for the system is to be selected such that the air will exit the coil at Td = 3°C & ° =...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...

6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
