A dehumidifier with a power requirement of 688.7 W is being installed in an office. The system takes in moist air with relative humidity of 85% at 98 kPa and 295 K at a rate of 0.15 kg/s. Assuming the system discharge the dehumidified air at 100 kPa. The heat loss of the system is measured to be 15 W. The condensate flow rate is 1.182 kg/hr at a temperature of 281 K. a) Calculate the mass flow rate of the dehumidified air at the outlet. b) Determine the humidity ratio at the system outlet. c) Show that the temperature of the dehumidified stream at the system outlet is given by, T- 336.04 - 0.01217 A (T T) d) Find the humidity ratio and the relative humidity of the flow at the outlet.

Good day. I am trying to review for examinations and require assistance for these questions... IHP: Under normal atmospheric conditions, a 6-cylinder engine has a bore of 6.28 inches and a stroke of 3.5 inches with an IMEP of 400 psi at 1825 rpm. Calculate the Indicated Horsepower of the engine in watts? BHP: Compute the brake horsepower of a four-cylinder engine that has a crankshaft turning at 2,500 rpm and a torque of 750 ft.lbs BMEP: Find the brake mean effective pressure of the Pratt and Whitney 14 cylinder engine having a 6 in stroke with a piston displacement of 1 litre and produces a torque of 84 N.m. with 3000 rpm. **Would appreciate a detailed explanation. Thank you so much.

STEP 2 Your first customer asked for an air piston-cylinder to use it in air compressors for generating high pressure. Your role in your company is to analyze, describe the operation of the system and their properties, explain and demonstrate the application of the first law of themodynamics to this system, as well as, illustrate the importance of expressions for work done in the system through the application of the first law. Describe the operation of the themodynamic system in Figure 1 and its properties, by constructing a P-V and T-V plots showing the process, the path, and the states then show the work under the curve on the P-V plot. STEP 3 Explain the application of the first law of thermodynamics to the system and explain the system parameters in terms of energy forms changes using the non-flow energy equation (NFEE) for the system and how they affect other parameters such as the final air temperature, by stating the appropriate assumptions and writing the general formula and…
