Exercise on Geothermal

Parameters Assumption

Area(km^2) Variable

Thickness(km) 1.5

Reservoir Temperature Variable

Reference Temperature 180

Rock Density 2700

Rock Specific Heat 0.90

Rock Porosity 0.05

Fluid Density 792 kg/m^3

Fluid Specific Heat Variable

Recovery Factor 15%

Conversion Efficiency 10%

Load Factor 75%

Plant life (years) 25

Additional data

Area = 8 km^2

Reservoir Temp =  250 0C

Fluid specific heat = 4180 Joules/kg 0C

Life of plant = 25 yrs x 365 days x 24 hrs x 60min x 60 sec

Compute for the following:

1.Etot

2.ER = Etot x Rec Factor

3.Ee = ER x Conversion Factor

4.MWt = Ee / Load factor x Plant life

I put Php10,000 into a fund today which earns 8% compounded annually. One year from now, I put in Php20,000. If I wish to withdraw my accumulated funds in five equal amounts starting 2 years from now, how much can I obtain on each withdrawal? 

Solve the following Problems. Situation 1 A 370-mm wide plank is cut in such a way that the width is in the tangential direction of annual rings. Compute the change in width as the moisture content changes from 18% to 42%. (The fiber saturation point is 35%, and it shrinks 8.21% in drying from FSP to oven dry in the tangential direction.) 

Solve the following Problems. Situation 1 A timber beam having a simple span of 4m carries a total load including its own weight of 15kN/m. It has a trapezoidal section having width of 250 mm at the top and 200 mm at the bottom and a depth of 360 mm, dressed dimension is used by reducing its dimensions by 15 mm. The wooden section is made up of 80% grade Apitong with the properties as follows: fb = 16.5 MPa fv = 1.75 MPa Compute the following: a. Maximum flexural stress b. Maximum shear stress

By referring to the figure below identify and discuss the factors that affect the adoption of new irrigation technologies. The discussion

should be arranged as per the categories of factors in the conceptual framework (e.g. individual factors should all be discussed under

the same sub-heading)
