1. Calculate the ventilation factor for a room with the following dimensions: 5m x 5m x 3.5 m. There is one vent in the room measuring 1.5m high by 4m wide.
2. Calculate the ventilation factor for a room with following dimensions: 5m x 5m x 3.5 m. There are two windows, each measuring 1.5 m high by 1 m wide and a door measuring 2.5 m high by 1.2 m wide.
3. Using Law's equation, calculate the maximum temperature reached in the room described in:
a. Question 1
b. Question 2
Calculate the minimum flow rate (m^3/hr) of river water needed to acheive pre cooling hot, pasteurized liquid prodcut assuming that 10% heat is lost to the surroundings during exchange and that the water temp after cooling should not exceed 25 deg..
Draw the given truss with all zero-bars removed. If the structure is stable and statically determinate, solve the forces in all of the bars of the truss using hand calculations. Indicate tension (T) or compression (C).
Detennine (1) the required shaker frequency to cause "resonance" and (2) the dynamic magnification ofresponse compared with static response for that level of damping.
Assume that the cable between B and the pulley remains vertical and solve for a given value of x.
A development is being planned within a 250-acre watershed. The present land use is 120 acres of pasture, with soil type B(CN=61), and the rest soil type D (CN=80). The Tc is 54 min. and the 2-year, 24-hour storm depth is 4 in.
You are designing a highway to AASHTO guidelines on a rolling terrain where the design speed will be 60 mi/h. at one section, a +1.0% grade and a -3.0% grade must be connected with an equal-tangent vertical curve.
What is the terminal settling velocity of a particle with a specific gravity of 1.4 and a diameter of 0.01 mm in 20 degrees celcius water?
Draw Mohr's circles of total and effective stresses and determine the magnitude of the principal effective stresses and direction of the major principal effective stresses.
A one tenth scale model of a soap box derby car is tested in a wind tunnel. The air speed in the wind tunnel is 70m/s, the air drag on the model car is 240 N, and the air temperature and pressure are identical to those expected
Based on experience, the geotechnical engineer estimated the coefficient of consolidation at 8 m2 per year. To limit settlement, a 4-m-high embankment will be constructed as a surcharge from fill of unit weight 16 kN/m3. Estimate the compression a..
A 12-oz serving of a regular beer contains 13 g of alcohol and 13 g of carbohydrates, and thus 150 Calories. A 12-oz serving of a light beer contains 11 g of alcohol and 5 g of carbohydrates, and thus 100 Calories.
The guy wires AB and AC are attached to the top of the transmission tower. The tension in cable AB is 8.6 kN. Determine the required tension T in cable AC such that the net effect of the two cables is a downward force at point A.
