In a single cylinder, four stroke, single acting gas engine, the cylinder diameter is 180 mm and the stroke is 350 mm . When running at 250 rpm , the mean area of the indicator diagram taken off the engine is 355 mm² , length of diagram 75 mm , scale of the indicator spring 90 kN/m sq per mm , and the number of explosions was counted to be 114 per minute. Calculate the indicated power.
so i have already asked this question and got a good answer, however on step 4, i dont understand how they reached 18.43 KW. When i do the math provided, i get the answer 7195.566. Where am i going wrong? thanks
StepsTo clarify how we determined the Indicated Power, I'll go over each step in detail.
Step 1: Comprehending the Provided Information - Cylinder diameter (in meters) = 180 mm = 0.18 m - Stroke length (in meters) = 350 mm = 0.35 m - Engine speed = 250 rpm -Indicator diagram mean area = 355 mm²
The diagram's length is 75 mm; its spring scale is 90 kN/m² per mm, or 90,000 N/m² per mm; and…

The combined weight of the acrobat and his balancing pole is 900 N, and the friction between his shoes and the rope is large enough to prevent him from slipping. Neglecting the weight of the rope and any elastic deformation, determine the deflection (y) and the tension in portion AC and BC of the rope for values of x from 0.5 m to 10 m using 0.5 m increments. 1.

- A block hangs from the end of bar AB that is 5.80 meters long and connected to the wall in the xz plane. The bar is supported at end A by a ball joint such that it carries only a compressive force along its axis. The bar is supported in equilibrium at end B by cables BD and BC that connect to the xz plane at points C and D respectively with coordinates given in the figure. The z components of the moments exerted on the bar by these two cables sum to 0. The tension in cable BD is measured to be 210 Newtons. Input answers of zero as 0.00 to avoid an invalid answer due to significant figures.

- In direct calorimetry, a person is placed in a large, water-insulated chamber. The chamber is kept at a constant temperature. While in the chamber, the subject is asked to perform a number of normal activities, such as eating, sleeping, and exercising. The rate of heat released from the subject’s body can be measured by the rate of heat gain by the water bath. Would direct calorimetry be a practical way to measure metabolic rate? Why or why not?A person is placed inside a calorimetric chamber for 24 hours. During this time, the 660-gallon water bath heats up by 3.2°F. What is the subject’s metabolic rate during this period? Report your answer in kcal/day. Assume that there is no heat loss from the water to the surroundings.arrow_forwardUpon reentry into the Earth’s atmosphere, the bottom of a space shuttle heats up to dangerous levels as the craft slows for landing.
