The minimum number of lighting fixtures in an Auditorium library was calculated to be 250 luminaires (in accordance with the BZ method).
The lighting fixtures used are 1x22-Watt LED (The lumens output of each LED lamp is 3000 lumens). The Utilization factor was found to be
0.55. What is the area of the Auditorium library? Assume a reduction factor of 1 and a depreciation factor of 1.5.

When Ibuprofen is given for fever to children 6 months of age up to 2 years, the usual dose is 5 milligrams (mg) per kilogram (kg) of body weight when the fever is under 102.5 degrees Fahrenheit.1) How much medicine would be usual dose for a 18 month old weighing 20 pounds? Hint: Use unit conversion to express the baby's weight in kg.
1.1. Compute the density (in units of m) of an ideal gas under the following
conditions:
(a) At 0 °C and 760 Torr pressure (1 Torr=1 mmHg). This is called the
Loschmidt number.
(b) In a vacuum of 103 Torr at room temperature (20 °C). This number is a
useful one for the experimentalist to know by heart (10 3 Torr 1 µ).
