3.10 As an anesthesiologist, you are responsible for preparing IV solutions containing various concentrations of
drugs. You have three continuous streams available in the operating room. The stream contents are listed with the
known mass fractions, where w₁, x is the mass fraction of compound x in stream i:
Stream 1: water, salt (w₁s = 0.010)
Stream 2: water, salt (w2,s = 0.020), drug A (w2, A = 0.10)
Stream 3: water, salt (w3,s = 0.020), drug A (w3, A = 0.050), drug B (w3,B = 0.080)
Your goal is to mix the above streams to produce an IV stream (Stream 4) under continuous operation that contains
water, salt, drug A, and drug B with the following characteristics:
■ Drug A has a mass fraction of 0.020 (W4,A = 0.020)
■ The ratio of the mass fraction of drug A to the mass fraction of drug B is 2.0
a. Diagram the system, including the streams. Label the system, system boundary, and surroundings.
b. State appropriate assumptions applied to the problem.

- room is to be maintained at 30% relative humidity and a dry-bulb temperature of 72ºF. The room has a sensible heat factor of 0.8 and a total hourly heating load of 200,000 Btu. A flow rate of 1000 cfm of outdoor air (at 20% relative humidity and a dry-bulb temperature of 40ºF) is used. In order to maintain adequate comfort, the supply air to the room is set to a dry-bulb temperature of 120ºF. To humidify the air, steam with a specific enthalpy of 1150 Btu per pound is utilized. Determine the wet bulb temperature, specific enthalpy, and volumetric flow rate of the supply air to the room. Can the supply air temperature values be obtained from the chart directly? show this on a psychrometric chart. Evaluate the increase in dry-bulb temperature as the air is sensibly heated, and the mass flow rate (in lb/hr) of steam required during the latent heating of the air. Calculate the heat added to the room during sensible heating (i.e., excluding humidification).arrow_forwardIn using the bolt cutter shown, a worker applies two forces P to the handles.
