An order calls for 6 grams of magnesium sulfate added to 500mL of NS infused at a rate of 1 g/hr. You have available 50%w/v magnesium sulfate vials. How many total milliosmoles (mOsm) are in the compounded solution? (MW MgSO4•7H20= 246.47, MW NaCl = 58.44) Please round the final answer to the nearest whole number

1. A 116 µF capacitor is connected to a source that operates at 90Hz with a peak potential difference of 24 V. Find the instantaneous power delivered to the capacitor at 2ms. (in W)
   
2. In an RLC series circuit, the source has a peak potential difference of 140V and a frequency of 65/πHz Take R=19Ω C=160μF, L=0.4H Find: the average power delivered by the source (in W)

1) Use dimensional analysis to find a relationship between the force of the wind, F, on a car. You will also need the velocity, v, the surface area of the car, A and the density of air, p.
.
2) Consider the problem of determining the terminal velocity of a raindrop falling from a motionless cloud. Determine a general model using dimensional analysis. Hint: You will need 5 parameters

A syngas fuel consists of these following volumetric composition: 75% methane and 25% butane. The syngas at 100 kg/hour and 25 C is mixed with 20% excess air at 30 C. Due to incomplete combustion mechanics, 10%v of the syngas carbon is partially oxidized and forms carbon monoxide.

If the products of combustion are at 600K, obtain the combustion heat transfer rate from the system.
