I need help calculating the corrected specific gravity

Urine from these constituents will be analyzed after you calculate Specific gravity of one urine solution. To do this simply follow instructions in Part B. A. Volume, Color, Turbidity, and Odor Use one of the graduated cylinders to determine the volume of the urine specimen. Calculate the rate of urine production in ml/minutes. The normal volume per 24 hours is 1 to 2 liters Also note the color, the presence of turbidity (cloudiness), and any odor. Normal urine is generally yellow to amber, is clear, and does not have a disagreeable odor. .Specific Gravity Specific gravity of a solution is the ratio of that solution relative to the weight of an identical volume of water. The normal range for specific gravity of urine is 1.010 to 1.030. The specific gravity of urine gives an estimate of the concentration of urinary solids. Long's coefficient (2.66) times the thousands grams digits (last two digits) of the specific gravity gives the estimate of total solids in per liter. A specific gravity of 1.018 gives an estimate of 47.88 grams/liter for urinary solids. Fill a urinometer cylinder to about 1 inch from the top with the collected urine. Holding the urinometer float by the stem, slowly insert it into the cylinder. Do not wet the stem above the water line or an inaccurate reading will result. Give the float a slight swirl and read the specific gravity from the graduated marks on the stem as it comes to rest. Do not accept a reading if the float is against the side of the cylinder. Read the specific gravity to the nearest 0.001 according to the scale. Read at the bottom of the meniscus. Also measure the temperature. The urinometer is calibrated at 15°C. For cach 3°C deviation above 15°Cadd 0.001 to the reading and subtract 0.001 from the reading for each 3oC below 15 °C. Rinse and carefully dry the urinometer and thermometer Measured specific gravity 1.018 Urine temperature 16 °C Corrected specific gravity Total solidsa lolDX 13-47 e YS q1L

Explanation / Answer

The Urinometer show an SpG of 1.018 and the urine temperature is 16 C which is 60.8 F.

we know that we need to ar 0.001 in the SpG for the change of every 5.4 F CHANGE IN temperature

but here the change is just 1.8 F that means we should 0.0003 to the SpG which will make no significant change in the SPG .

Hence the corrected SpG remains the same 1.018
